The University of Oxford research group led by OQC CSO Dr. Peter Leek today announced research demonstrating a fundamental speedup of the controlled-Z gate in superconducting qubits reaching a fidelity of 99.8% in only 25 ns.

Qolab, Inc., a leading innovator in quantum computing hardware, today announced an investment from Applied Ventures, LLC, the venture capital arm of Applied Materials, Inc. This Series A investment marks a significant milestone in the collaboration between Qolab and Applied Materials to accelerate the development and scalable manufacturing of superconducting qubits.

Rigetti Computing, Inc. (“Rigetti” or the “Company”), a pioneer in full-stack quantum-classical computing, today announced that it has entered into a strategic collaboration agreement with Quanta Computer Inc., (“Quanta”) a Taiwan-based Global Fortune 500 company and the global leader of computer server manufacturing, to accelerate the development and commercialization of superconducting quantum computing.

Qubits—the fundamental units of quantum information—drive entire tech sectors. Among them, superconducting qubits could be instrumental in building a large-scale quantum computer, but they rely on electrical signals and are difficult to scale. In a breakthrough, a team of physicists at the Institute of Science and Technology Austria (ISTA) has achieved a fully optical readout of superconducting qubits, pushing the technology beyond its current limitations. Their findings were published in Nature Physics.

A new study has uncovered important behavior in the flow of electric current through superconductors, potentially advancing the development of future technologies for controlled quantum information processing. The study is co-authored by Babak Seradjeh, Professor of Physics within the College of Arts and Sciences at Indiana University Bloomington, with theoretical physicists Rekha Kumari and Arijit Kundu of the Indian institute of Technology Kanpur. While the study is theoretical, the research team confirmed their results through numerical simulations. Published in Physical Review Letters, the world’s premier physics journal, the research focuses on “Floquet Majorana fermions” and their role in a phenomenon called the Josephson effect, which could lead to more precise control of the dynamics of driven quantum systems.

erra Quantum, a global leader in quantum technology, today announced the successful demonstration of a new type of superconductivity – a significant breakthrough in physics and superconducting technology. “Type III” superconductors feature superconducting islands separated by non-superconducting regions, resulting in unique magnetic and electrical properties.

Together with 24 German research institutions and companies under the coordination of Forschungszentrum (FZ) Jülich, Fraunhofer IPMS is working on an integrated German quantum computer based on superconducting quantum chips and with improved error rates. Halfway through the project, the first demonstrator can now be put into operation.

Now, researchers have observed that a necessary characteristic of a superconductor – called electron pairing – occurs at much higher temperatures than previously thought, and in a material where one least expects it – an antiferromagnetic insulator. Although the material did not have zero resistance, this finding suggests researchers might be able to find ways to engineer similar materials into superconductors that operate at higher temperatures.

VTT Technical Research Centre of Finland begins searching for an innovation partner to scale up Finland’s next quantum computer, aiming towards 300 qubits. In the innovative co-development project, VTT will also be researching methods for how the developed quantum computer can be optimised for solving mathematical problems typical for new material development.
