NVIDIA today announced it is building a Boston-based research center to provide cutting-edge technologies to advance quantum computing. The NVIDIA Accelerated Quantum Research Center, or NVAQC, will integrate leading quantum hardware with AI supercomputers, enabling what is known as accelerated quantum supercomputing. The NVAQC will help solve quantum computing's most challenging problems, ranging from qubit noise to transforming experimental quantum processors into practical devices.

Leading quantum computing innovators, including Quantinuum, Quantum Machines and QuEra Computing, will tap into the NVAQC to drive advancements through collaborations with researchers from leading universities, such as the Harvard Quantum Initiative in Science and Engineering (HQI) and the Engineering Quantum Systems (EQuS) group at the Massachusetts Institute of Technology (MIT).

China's Ministry of Finance has allocated $55 billion (¥398.12 billion) for science and technology funding in 2025, marking a 10% increase from the previous year's $50 billion (¥361.9 billion). This expenditure now stands as the nation's third-largest budget item, following only national defense and debt interest payments. The 2024 allocation achieved a 97.6% implementation rate, indicating effective deployment of resources in the technology sector. The funding prioritizes initiatives under the "Science and Technology Innovation 2030" program, with significant investments targeting semiconductors, artificial intelligence, and quantum computing research. Rather than stimulating immediate breakthroughs, the incremental funding increase aims to strengthen existing projects and enhance technological self-reliance amid global competition.

This strategy shows some fiscal constraints imposed by China's economic slowdown while maintaining the country's long-term technological objectives. Supplementary measures bolster direct R&D investment, including enhanced support for fundamental research and specialized financing mechanisms for technology-focused enterprises. Tax reductions and targeted subsidies form part of a comprehensive policy framework designed to foster domestic innovation capabilities. While the funding increase shows commitment to technological advancement, effective project management and efficient resource allocation will be critical success factors, mainly as China competes more globally. Perhaps the most important milestone for this aid package will be supporting the development of advanced lithography tools to make sure that domestic companies can manufacture cutting-edge silicon.

It plugs into a standard power socket, operates at just 1600 W, and delivers on-demand quantum computing for computationally intensive workloads.

Microsoft launched its Majorana 1 chip—the world's first quantum processor powered by a Topological Core architecture—last month. The company's debuting of its Majorana design was celebrated as a significant milestone—in 2023, an ambitious roadmap was published by Microsoft's research department. At the time, a tall Majorana particle-based task was set: the building of a proprietary quantum supercomputer within a decade. Returning to the present day; outside parties have criticized Microsoft's February announcements. The Register published an investigative piece earlier today, based on quotes from key players specializing in the field of Quantum studies. Many propose a theoretical existence of Majorana particles, while Microsoft R&D employees have claimed detection and utilization. The Register referred back to recent history: "(Microsoft) made big claims about Majorana particles before, but it didn't end well: in 2021 Redmond's researchers retracted a 2018 paper in which they claimed to have detected the particles."

As pointed out by Microsoft researcher Chetan Nayak; their latest paper was actually authored last March 2024, but only made public in recent weeks. Further details of progress are expected next week, at the American Physical Society (APS) 2025 Joint March Meeting. The Register has compiled quotes from vocal critics; starting with Henry Legg—a lecturer in theoretical physics at the University of St Andrews, Scotland. The noted scholar believes—as divulged in a scientific online comment—that Microsoft's claimed Quantum breakthrough: "is not reliable and must be revisited." Similarly, collaborators from Germany's Forschungszentrum Jülich institute and the University of Pittsburgh, USA released a joint video statement. (Respectively) Experimental physicist Vincent Mourik and by Professor Sergey Frolov outlined: "distractions caused by unreliable scientific claims from Microsoft Quantum."

VTT Technical Research Centre of Finland and IQM Quantum Computers, one of the global leaders in superconducting quantum computers, have completed and launched Europe's first 50-qubit superconducting quantum computer, now open to researchers and companies through the VTT QX quantum computing service.

The new 50-qubit quantum computer further strengthens Finland's position among the countries capable of developing and investing in quantum computing. Finland first announced its efforts in quantum computing development back in November 2020 with a total budget of EUR 20.7 million from the Finnish government to develop a 50-qubit quantum computer.

Today, Amazon Web Services (AWS) announced Ocelot, a new quantum computing chip that can reduce the costs of implementing quantum error correction by up to 90%, compared to current approaches. Developed by the team at the AWS Center for Quantum Computing at the California Institute of Technology, Ocelot represents a breakthrough in the pursuit to build fault-tolerant quantum computers capable of solving problems of commercial and scientific importance that are beyond the reach of today's conventional computers.

AWS used a novel design for Ocelot's architecture, building error correction in from the ground up and using the 'cat qubit'. Cat qubits-named after the famous Schrödinger's cat thought experiment-intrinsically suppress certain forms of errors, reducing the resources required for quantum error correction. Through this new approach with Ocelot, AWS researchers have, for the first time, combined cat qubit technology and additional quantum error correction components onto a microchip that can be manufactured in a scalable fashion using processes borrowed from the microelectronics industry.

Microsoft has launched Majorana 1, the world's first quantum processor powered by a Topological Core architecture, marking a significant step toward fault-tolerant, utility-scale quantum computing. The chip leverages tetron qubits—topological qubits built on Majorana zero modes (MZMs)—to achieve stability and scalability, with a roadmap to one million qubits, a threshold critical for solving industrial challenges like microplastic degradation and self-healing materials. At the heart of Majorana 1 lies a superconductor-semiconductor heterostructure combining indium arsenide and aluminium. This "topoconductor" material enables precise control of MZMs, exotic quantum particles that encode information non-locally, inherently resisting noise and errors. The design, detailed in the latest paper, arranges MZMs in H-shaped nanowires, forming two-sided tetrons that suppress errors exponentially via three factors: topological gap-to-temperature ratio, wire length-to-coherence length, and high-fidelity microwave readout. Microsoft claims that thopoconductor can "create an entirely new state of matter - not a solid, liquid or gas but a topological state."

Unlike conventional qubits requiring analog tuning, Microsoft's architecture uses digital voltage pulses for error-resistant, measurement-based operations. This approach simplifies scaling, with the current chip housing eight tetrons and supporting protocols for quantum error detection, such as the Hastings-Haah Floquet codes and ladder codes outlined in Microsoft's technical roadmap. These codes rely on single- and two-qubit Pauli measurements, native to tetrons, to detect and correct errors without complex gate sequences. DARPA's US2QC program validated that Microsoft's topology-first strategy minimizes overhead, enabling a future million-qubit system compact enough to fit in Azure datacenters. The chip's quantum capacitance measurement system detects parity shifts in microseconds, achieving a signal-to-noise ratio critical for fault tolerance. Applications span designing catalysts to break down pollutants, optimizing enzymes for agriculture, and simulating novel materials. Microsoft aims to merge quantum, AI, and high-performance computing into Azure, accelerating discoveries once deemed decades away. Majorana 1 proves that topological qubits—once a high-risk bet—are now the cornerstone of scalable quantum systems.

Quantum computing is one of the most exciting areas in computer science, promising progress in accelerated computing beyond what's considered possible today. It's expected that the technology will tackle myriad problems that were once deemed impractical or even impossible to solve. Quantum computing promises huge leaps forward for fields spanning drug discovery and materials development to financial forecasting.

But just as exciting as quantum computing's future are the breakthroughs already being made today in quantum hardware, error correction and algorithms.

Imec, a world-leading research and innovation hub in nanoelectronics and digital technologies, today announced the demonstration of high quality 300 mm-Si-based quantum dot spin qubit processing with devices resulting in a statistically relevant, average charge noise of 0.6µeV/√ Hz at 1 Hz. In view of noise performance, the values obtained are the lowest charge noise values achieved on a 300 mm fab-compatible platform.

Such low noise values enable high-fidelity qubit control, as reducing the noise is critical for maintaining quantum coherence and high fidelity control. By demonstrating those values, repeatedly and reproducibly, on a 300 mm Si MOS quantum dot process, this work makes large-scale quantum computers based on Si quantum dots a realistic possibility.
