A team of researchers from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences and its partners have made significant advancements in random quantum circuit sampling with Zuchongzhi-3, a superconducting quantum computing prototype featuring 105 qubits and 182 couplers. Operating at a speed 10¹⁵ times faster than the most powerful supercomputer currently available and one million times faster than Google's latest published results, the achievement marks a major milestone in quantum computing and follows the success of its predecessor, Zuchongzhi-2.

QuantWare, the quantum computing company building technology to create the world’s most powerful quantum processors, has raised a €20 million Series A round.

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.

Quantum Machines (QM), a leading provider of advanced quantum control solutions, today announced it has raised $170 million in Series C funding, bringing the company’s total funding to date to $280 million. The investment comes as the majority of quantum computing companies now rely on QM’s technology to build and scale their systems. The highly oversubscribed round was led by PSG Equity with participation from Intel Capital, Red Dot Capital Partners, and existing investors, and marks one of the largest rounds of funding in the quantum industry.

In new work, using a superconducting qubit called fluxonium, MIT researchers in the Department of Physics, the Research Laboratory of Electronics (RLE), and the Department of Electrical Engineering and Computer Science (EECS) developed two new control techniques to achieve a world-record single-qubit fidelity of 99.998 percent. This result complements then-MIT researcher Leon Ding’s demonstration last year of a 99.92 percent two-qubit gate fidelity.

The U.S. National Science Foundation has launched six pilot projects to bridge scientific gaps between current quantum technological capabilities and those needed to fully harness quantum properties of energy and matter for practical uses. The six projects join five others that the agency announced in August. Collectively, they are supported by the NSF National Quantum Virtual Laboratory (NSF NQVL) initiative, an ambitious effort to accelerate the development of quantum technologies by providing researchers anywhere in the U.S. with access to specialized resources.

Alice & Bob, a global frontrunner in the race for fault-tolerant quantum computing, has unveiled its white paper and five-year roadmap. The white paper outlines a clear path to achieving useful quantum computing through Alice & Bob’s cat qubit technology, which promises to deliver high-fidelity logical qubits while using significantly fewer hardware and energy resources compared to alternative approaches.

In September Microsoft announced their collaboration with Atom Computing to build the world’s most powerful quantum machine, and create a unique commercial offering which is available for order today. Just two months after this announcement they are excited to share the news that together they have now entangled 24 logical qubits, setting a new world record. They also jointly demonstrated error detection, correction, and computation with 28 logical qubits on Atom’s flagship systems.

planqc has been selected to lead a €20 million project to build and deploy a 1,000-qubit quantum computer at the Leibniz Supercomputing Centre (LRZ) in Garching near Munich. This advanced quantum computer, based on neutral atoms, will be integrated into LRZ’s high-performance computing (HPC) infrastructure, serving as an accelerator for scientific research and towards industrial applications.

IQM Quantum Computers (IQM), a global leader in designing, building, and selling superconducting quantum computers, today announced the company has won a contract to deliver the Czech Republic’s first quantum computer to be installed at the IT4Innovations National Supercomputing Centre in Ostrava.
