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.

Infleqtion, a global leader in quantum information technologies, today announced a key milestone in the Scalable Quantum Atomic Lattice computing tEstbed (SQALE) project—the successful demonstration of a 16x16 neutral atom array—the largest reported array of its kind in the UK. This achievement is a crucial step toward building scalable quantum processors capable of supporting fault-tolerant quantum computing.

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.

Rigetti Computing, Inc. , a pioneer in full-stack quantum-classical computing, announced today the public launch of its 84-qubit Ankaa-3 system. Ankaa-3 is Rigetti’s newest flagship quantum computer featuring an extensive hardware redesign that enables superior performance. Rigetti also celebrates major two-qubit gate fidelity milestones with Ankaa-3: successfully halving error rates in 2024 to achieve a median 99.0% iSWAP gate fidelity, as well as demonstrating 99.5% median fidelity fSim gates.

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.

Oxford Ionics, a world leader in trapped-ion quantum computing, today announced that it has won a contract, alongside Infineon Technologies AG, to build a state-of-the-art portable quantum computer for Agentur für Innovation in der Cybersicherheit GmbH, or 'Cyberagentur'. Oxford Ionics and Infineon are one of three independent contractors selected by Cyberagentur, who is investing a total of €35M into the project.

IonQ, a leader in the quantum computing industry, recently announced that it has surpassed “three 9’s” (99.9%) two-qubit gate fidelity on one of its next-generation barium development platforms. T

Oxford Ionics, a leader in trapped-ion quantum computing, today announced it has set a new record in quantum state preparation and measurement (SPAM). The results, experimentally implemented at the University of Oxford, demonstrate the highest recorded SPAM fidelities of any quantum computing platform at 99.9993%.

IQM Quantum Computers, a global leader in building quantum computers, has reached significant milestones in superconducting quantum computing, demonstrating improvements in two key metrics characterising the quality of quantum computer.

Oxford Ionics, a world leader in trapped-ion quantum computing, today announced it has been selected by the United States’ Defense Advanced Research Projects Agency (DARPA) for its Quantum Benchmarking Initiative (QBI).
