Today at its inaugural IBM Quantum Developer Conference, IBM announced quantum hardware and software advancements to execute complex algorithms on IBM quantum computers with record levels of scale, speed, and accuracy.

IBM Quantum Heron, the company's most performant quantum processor to-date and available in IBM's global quantum data centers, can now leverage Qiskit to accurately run certain classes of quantum circuits with up to 5,000 two-qubit gate operations. Users can now use these capabilities to expand explorations in how quantum computers can tackle scientific problems across materials, chemistry, life sciences, high-energy physics, and more.

The EuroHPC Joint Undertaking (EuroHPC JU) has signed a purchase agreement with IQM Quantum Computers (IQM), a global leader in designing, building, and selling superconducting quantum computers. Under the agreement, IQM will deliver two advanced Radiance quantum systems of 54 qubits and 150 qubits in the second half of 2025 and by the end of 2026, respectively.

The two distinct systems, featuring high-quality qubits and industry-leading fidelities will play a pivotal role in executing quantum algorithms across a range of application domains.

In developing the OPX1000, a controller fit for the ever-growing quantum processors counting 1,000 qubits and beyond, we had to think deeply about every detail that impairs scalability. Our recently unveiled OPX1000 module for microwave generation (MW-FEM) generates pulses up to 10.5 GHz directly, without analog oscillators or mixers. The choice of technology to reach microwave frequencies is not trivial. We choose cutting-edge direct digital synthesis (DDS) for very specific reasons, and we believe it will enable scalability and performance to an even greater degree. In this blog, we dive deeper into the considerations for going this route and existing alternatives. So stick around, whether you like mixers or hate them, this will be an interesting ride.

Summary of Technologies for Microwave Operation
The control signals for qubit drive and readout often fall in the microwave range, which is outside the range of baseband controllers. Many qubit labs have solved the issue with solutions based on mixing, including single sideband mixers, IQ-mixers, or more complicated schemes such as double super-heterodyne (DSH) conversion. Mixer-based solutions make use of analog local oscillators (LOs) that are multiplied by the signal of a controller or an AWG. IQ-mixers naturally suffer from two main spurs (affectionate name for unwanted signals), the LO leakage and the mixer image, which require non-trivial calibration to be removed. Other schemes, such as double super-heterodyne, offer a zero-calibration solution but use many more components. Additionally, mixing schemes require having an LO source per mixer if different drive frequencies are used. Having a low phase source per mixer is very expensive, and in order to cut prices, will probably include a phase-lock loops (PLL), leading to phase differences between channels, which is detrimental for multi-qubit systems. In other words, while mixers can be useful, we need to be aware of the pros and cons involved.

With computation potential far beyond current supercomputers, quantum computers are the subject of enthusiastic research and development worldwide. In 2023, Academia Sinica successfully overcame various bottlenecks in the fabrication, control, and measurement of quantum chips.

Alice & Bob, a leading hardware developer in the race to fault tolerant quantum computers, today announced the tape out of a new chip expected to improve error rates with every qubit added, making it a prototype for the company's first error-corrected, logical qubit.

The 16-qubit quantum processing unit (QPU), Helium 1, is the first chip in Alice & Bob's roadmap combining cat qubits to run an error correction code. The company will be able to use this platform to create its first logical qubit with error rates lower than any existing single physical qubit. With the tape-out complete, the chip enters a characterization and calibration phase that will be followed by a release on the cloud.

The Platform for Digital and Quantum Innovation of Quebec (PINQ²), a non-profit organization (NPO) founded by the Ministry of Economy, Innovation and Energy of Quebec (MEIE - ministère de l'Économie, de l'Innovation et de l'Énergie du Québec) and the Université de Sherbrooke, along with IBM, are proud to announce the historic inauguration of an IBM Quantum System One at IBM Bromont. This event marks a major turning point in the field of information technology and all sectors of innovation in Quebec, making PINQ² the sole administrator to inaugurate and operate an IBM Quantum System One in Canada. To date, this is one of the most advanced quantum computers in IBM's global fleet of quantum computers.

This new quantum computer in Quebec reinforces Quebec's and Canada's position as a force in the rapidly advancing field of quantum computing, opening new prospects for the technological future of the province and the country.

International Data Corporation (IDC) today published its second forecast for the worldwide quantum computing market, projecting customer spend for quantum computing to grow from $1.1 billion in 2022 to $7.6 billion in 2027. This represents a five-year compound annual growth rate (CAGR) of 48.1%. The forecast includes base quantum computing as a service as well as enabling and adjacent quantum computing as a service.

The new forecast is considerably lower than IDC's previous quantum computing forecast, which was published in 2021. In the interim, customer spend for quantum computing has been negatively impacted by several factors, including: slower than expected advances in quantum hardware development, which have delayed potential return on investment; the emergence of other technologies such as generative AI, which are expected to offer greater near-term value for end users; and an array of macroeconomic factors, such as higher interest and inflation rates and the prospect of an economic recession.

Today, it was announced that Rensselaer Polytechnic Institute will become the first university in the world to house an IBM Quantum System One. The IBM quantum computer, intended to be operational by January of 2024, will serve as the foundation of a new IBM Quantum Computational Center in partnership with Rensselaer Polytechnic Institute (RPI). By partnering, RPI's vision is to greatly enhance the educational experiences and research capabilities of students and researchers at RPI and other institutions, propel the Capital Region into a top location for talent, and accelerate New York's growth as a technology epicenter.

RPI's advance into research of applications for quantum computing will represent a more than $150 million investment once fully realized, aided by philanthropic support from Curtis R. Priem '82, vice chair of RPI's Board of Trustees. The new quantum computer will be part of RPI's new Curtis Priem Quantum Constellation, a faculty endowed center for collaborative research, which will prioritize the hiring of additional faculty leaders who will leverage the quantum computing system.

Earlier this week Microsoft revealed its roadmap for the building of a proprietary quantum supercomputer. The company's research department has been making progress with the elusive building blocks of topological qubits over a number of years. Microsoft's VP of advanced quantum development - Krysta Svore - has informed TechCrunch that their team anticipates it taking under ten years to construct and complete a quantum supercomputer utilizing qubits, with a view to perform a reliable one million quantum operations per second. Svore stated: "We think about our roadmap and the time to the quantum supercomputer in terms of years rather than decades."

Majorana-based qubits are extremely difficult to create, but worth the effort due to being inherently stable. Microsoft's quantum team has dedicated itself to hitting a first milestone, with more devices developed and data collected since last year's major breakthrough. Svore reiterates: "Today, we're really at this foundational implementation level...We have noisy intermediate-scale quantum machines. They're built around physical qubits and they're not yet reliable enough to do something practical and advantageous in terms of something useful. For science or for the commercial industry. The next level we need to get to as an industry is the resilient level. We need to be able to operate not just with physical qubits but we need to take those physical qubits and put them into an error-correcting code and use them as a unit to serve as a logical qubit." Svore's team is focusing more on the building of hardware-protected qubits, that are tiny - "smaller than 10 microns on a side" with performance of one qubit operation in less than a microsecond.

Researchers at Toshiba Corporation have achieved a breakthrough in quantum computer architecture: the basic design for a double-transmon coupler that will improve the speed and accuracy of quantum computation in tunable couplers. The coupler is a key device in determining the performance of superconducting quantum computers.

Tunable couplers in a superconducting quantum computer link two qubits and perform quantum computations by turning on and off the coupling between them. Current technology can turn off the coupling of transmon qubits with close frequencies, but this is prone to crosstalk errors that occur on one of the qubits when the other qubit is irradiated with electromagnetic waves for control. In addition, current technology cannot completely turn off coupling for qubits with significantly different frequencies, resulting in errors due to residual coupling.

Baidu, Inc., a leading AI company with strong Internet foundation, today announced its first superconducting quantum computer that fully integrates hardware, software, and applications. On top of this, Baidu also introduced the world's first all-platform quantum hardware-software integration solution that provides access to various quantum chips via mobile app, PC, and cloud. Launched at Quantum Create 2022, a quantum developer conference held in Beijing, this new offering paves the way for the long-awaited industrialization of quantum computing.

A revolutionary technology that harnesses the laws of quantum mechanics to solve problems beyond the reach of classical computers, quantum computing is expected to bring ground-breaking transformations in fields like artificial intelligence (AI), computational biology, material simulation, and financial technology. However, a significant gap remains between quantum devices and services.

Quantum computing is an upcoming acceleration aiding classical computational methods to achieve monumental speed-ups at a few select problems. Unlike classical computers, quantum systems usually require sub-ambient cooling to make them work. At Quantum Brilliance, an Australian-Germany startup company, researchers have been developing quantum accelerators based on diamonds. Today, we got the world's first installation of room-temperature on-premises quantum computers at Australia's Pawsey Supercomputing Centre. While we don't have much information about the computational capability of the system, we know that it is paired with HPE Setonix, Pawsey's HPE Cray EX supercomputer.

In a brief YouTube video shared by Pawsey, it is highlighted that the benefits of using quantum accelerators are real, and they are figuring out ways to integrate it with the center's hardware and software stack for better usage. Meanwhile, Quantum Brilliance diamond accelerators are still a black box of some sort as the technology is known to the startup and its collaborating Australian universities. All we know is that the company is harnessing nitrogen-vacancy (NV) center in diamonds, which supposedly have the longest coherence time of any room temperature quantum state. This translates to a qubit that can operate anywhere a classical computer can.

IonQ, an industry leader in quantum computing, announced IonQ Forte, its latest generation of quantum systems. The system features novel, cutting-edge optics technology that enables increased accuracy and further enhances IonQ's industry leading system performance. Forte is expected to be initially available for select developers, partners, and researchers in 2022 and is expected to be available for broader customer access in 2023. Forte is the latest evolution towards a "software-configurable quantum computer," which is designed to allow the company to optimize the computing hardware for targeted user problems-ultimately, giving users customized algorithmic performance. The new system features acousto-optic deflector (AOD) technology, which allows IonQ to dynamically direct laser beams that drive quantum gates towards individual ions. The AOD is designed to minimize noise and overcome variations in ion position, improving fidelity in long chains of trapped ions, which is crucial for scaling quantum computers. In addition, key parameters, including qubit and gate configuration, can be tailored to user needs, creating a truly dynamic and flexible system.

Forte joins IonQ Aria as the company's second system with capacity of up to 32 qubits, has AOD systems capable of addressing up to 40 individual ion qubits, and is currently configured to use 31 of them. With this technological leap, IonQ furthers its commitment to building ever more powerful quantum computers with an increasing number of algorithmic qubits, an application-oriented performance metric for quantum computers. The new announcement follows IonQ's announcement of open-source access to native gates, which allows quantum application developers to explore software breakthroughs on top of IonQ hardware without having to choose from a set menu of gates.

Fujitsu has successfully developed the world's fastest quantum computer simulator capable of handling 36 qubit quantum circuits on a cluster system featuring Fujitsu's "FUJITSU Supercomputer PRIMEHPC FX 700" ("PRIMEHPC FX 700")(1), which is equipped with the same A64FX CPU that powers the world's fastest supercomputer, Fugaku.

The newly developed quantum simulator can execute the quantum simulator software "Qulacs"(3) in parallel at high speed, achieving approximately double the performance of other significant quantum simulators in 36 qubit quantum operations. Fujitsu's new quantum simulator will serve as an important bridge towards the development of quantum computing applications that are expected to be put to practical use in the years ahead.

IBM today announced that LG Electronics has joined the IBM Quantum Network to advance the industry applications of quantum computing.

IBM today announced its new 127-quantum bit (qubit) 'Eagle' processor at the IBM Quantum Summit 2021, its annual event to showcase milestones in quantum hardware, software, and the growth of the quantum ecosystem. The 'Eagle' processor is a breakthrough in tapping into the massive computing potential of devices based on quantum physics. It heralds the point in hardware development where quantum circuits cannot be reliably simulated exactly on a classical computer. IBM also previewed plans for IBM Quantum System Two, the next generation of quantum systems.

Quantum computing taps into the fundamental quantum nature of matter at subatomic levels to offer the possibility of vastly increased computing power. The fundamental computational unit of quantum computing is the quantum circuit, an arrangement of qubits into quantum gates and measurements. The more qubits a quantum processor possesses, the more complex and valuable the quantum circuits that it can run.

At an Intel Labs virtual event today, Intel unveiled Horse Ridge II, its second-generation cryogenic control chip, marking another milestone in the company's progress toward overcoming scalability, one of quantum computing's biggest hurdles. Building on innovations in the first-generation Horse Ridge controller introduced in 2019, Horse Ridge II supports enhanced capabilities and higher levels of integration for elegant control of the quantum system. New features include the ability to manipulate and read qubit states and control the potential of several gates required to entangle multiple qubits.

"With Horse Ridge II, Intel continues to lead innovation in the field of quantum cryogenic controls, drawing from our deep interdisciplinary expertise bench across the Integrated Circuit design, Labs and Technology Development teams. We believe that increasing the number of qubits without addressing the resulting wiring complexities is akin to owning a sports car, but constantly being stuck in traffic. Horse Ridge II further streamlines quantum circuit controls, and we expect this progress to deliver increased fidelity and decreased power output, bringing us one step closer toward the development of a 'traffic-free' integrated quantum circuit."-Jim Clarke, Intel director of Quantum Hardware, Components Research Group, Intel.

Honeywell, a multinational conglomerate specializing in the quantum computing field, today announced they have created the world's most advanced quantum computer. Their new solution brings about a quantum computing volume set at 64 - twice the quantum volume of the world's previous most powerful quantum computer, the IBM Raleigh. You might be looking at that 64 quantum volume, wondering what that means - and where did the qubits metric go. Well, the thing with quantum computers is that the number of qubits can't really be looked at as a definite measure of performance - instead, it's just a part of the "quantum volume" calculation, which expresses the final performance of a quantum system.

When you make operations at the quantum level, a myriad of factors come into play that adversely impact performance besides the absolute number of qubits, such as the calculation error rate (ie, how often the system outputs an erroneous answer to a given problem) as well as the qubit connectivity level. Qubit connectivity expresses a relationship between the quantum hardware capabilities of a given machine and the ability of the system to distribute workloads across qubits - sometimes the workloads can only be distributed to two adjacent qubits, other times, it can be distributed to qubits that are more far apart within the system without losing data coherency and without affecting error rates - thus increasing performance and the systems' flexibility towards processing workloads. If you've seen Alex Garland's Devs series on Hulu (and you should; it's great), you can see a would-be-quantum computer and all its intricate connections. Quantum computers really are magnificent crossovers of science, materials engineering, and computing. Of course, the quantum computing arms race means that Honeywell's system will likely be dethroned by quantum volume rather soon.

Intel, in collaboration with QuTech, today published a paper in Nature demonstrating the successful control of "hot" qubits, the fundamental unit of quantum computing, at temperatures greater than 1 kelvin. The research also highlighted individual coherent control of two qubits with single-qubit fidelities of up to 99.3%. These breakthroughs highlight the potential for cryogenic controls of a future quantum system and silicon spin qubits, which closely resemble a single electron transistor, to come together in an integrated package.

"This research represents a meaningful advancement in our research into silicon spin qubits, which we believe are promising candidates for powering commercial-scale quantum systems, given their resemblance to transistors that Intel has been manufacturing for more than 50 years. Our demonstration of hot qubits that can operate at higher temperatures while maintaining high fidelity paves the way to allow a variety of local qubit control options without impacting qubit performance," said Jim Clarke, director of quantum hardware, Intel Labs.

Intel researchers are taking new steps toward quantum computers by testing a tiny new "spin qubit" chip. The new chip was created in Intel's D1D Fab in Oregon using the same silicon manufacturing techniques that the company has perfected for creating billions of traditional computer chips. Smaller than a pencil's eraser, it is the tiniest quantum computing chip Intel has made.

The new spin qubit chip runs at the extremely low temperatures required for quantum computing: roughly 460 degrees below zero Fahrenheit - 250 times colder than space. The spin qubit chip does not contain transistors - the on/off switches that form the basis of today's computing devices - but qubits (short for "quantum bits") that can hold a single electron. The behavior of that single electron, which can be in multiple spin states simultaneously, offers vastly greater computing power than today's transistors, and is the basis of quantum computing.
