MIT researchers developed a photon-shuttling “interconnect” that can facilitate remote entanglement, a key step toward a practical quantum computer.

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.

QuamCore, a deep tech startup redefining quantum computing scalability, announced today its emergence from stealth with $9 million in seed funding. Founded in 2022, QuamCore has spent the past two years developing its breakthrough superconducting quantum processor architecture, working in stealth mode to solve the critical scalability challenges that have long prevented practical quantum computing. The company has now emerged with a patented architecture that enables the integration of 1 million qubits into a single cryostat - a milestone previously thought impossible. This breakthrough dramatically reduces the size, energy consumption, and cost of quantum computers, unlocking practical applications across pharmaceuticals, AI, materials science, and energy.

OQC, a global leader in quantum computing solutions and spin-out from Oxford University’s Department of Physics, recently announced their research on the ‘Integration of through-sapphire substrate machining with superconducting quantum processors’. Successful demonstrations of this technique have been shown through the complete manufacturing process of their 32-qubit OQC Toshiko QPU.

If you’d like to solve a math problem on a good old-fashioned chalkboard, you want the board clean and free of any previous markings so that you have space to work. Quantum computers have a similar need for a clean workspace, and a team including scientists at the National Institute of Standards and Technology (NIST) and University of Maryland have found an innovative and effective way to create and maintain it.

Researchers at the University of Chicago Pritzker School of Molecular Engineering have realized a new design for a superconducting quantum processor—aiming at a potential architecture for the large-scale, durable devices the quantum revolution demands.

Qolab, Inc. a leader in superconducting quantum computing, announced today that it secured over $16.0 million to date in its Series A financing round, led by Octave Ventures with co-investment from the Development Bank of Japan Inc. (DBJ), Wisconsin Alumni Research Foundation (WARF), and Phoenix Venture Partners. This investment represents a significant step in Qolab’s mission to develop utility-scale quantum computing technology by advancing scalability in quantum systems.

Researchers from Singapore and China have used a superconducting quantum processor to study the phenomenon of quantum transport in unprecedented detail.

Researchers from the RIKEN Center for Quantum Computing and Toshiba have succeeded in building a quantum computer gate based on a double-transmon coupler (DTC), which had been proposed theoretically by Hayato Goto, Senior Fellow at Toshiba, as a device that could significantly enhance the fidelity of quantum gates. Using this, they achieved a fidelity of 99.90 percent for a two-qubit device known as a CZ gate and 99.98 percent for a single-qubit gate. This breakthrough, which was carried out as part of the Q-LEAP project, not only boosts the performance of existing noisy intermediate-scale quantum (NISQ) devices but also helps pave the way for the realization of fault-tolerant quantum computation through effective quantum error correction.

SDT, a quantum standard technology company, has announced plans to establish a joint venture with Anyon Technologies, a leading quantum computing firm, by the end of this year. The collaboration aims to develop and produce a 20-qubit superconducting quantum computer system integrated with NVIDIA’s Grace Hopper Superchip.
