A superconducting quantum computer, fully designed and built with domestic Japanese components and software, went live on July 28 at The University of Osaka’s Center for Quantum Information and Quantum Biology (QIQB). This achievement, a […]
How can quantum technologies be developed responsibly? In the journal Science, researchers from the Technical University of Munich (TUM), the University of Cambridge, Harvard University and Stanford University argue that international standards should be established […]
“Happy 100th birthday, quantum mechanics!” a physicist bellowed into a microphone one evening in June, and the cavernous banquet hall of Hamburg’s Hotel Atlantic erupted into cheers and applause. Some 300 quantum physicists had traveled […]
Quantum 9, 1827 (2025). https://doi.org/10.22331/q-2025-08-08-1827 We propose an experimental setup to probe the interplay between the quantum superposition principle and gravitational time dilation arising from the mass-energy equivalence. It capitalizes on state-of-the-art atom interferometers that […]
Quantum 9, 1826 (2025). https://doi.org/10.22331/q-2025-08-08-1826 We introduce a new class of qubit codes that we call Evenbly codes, building on a previous proposal of hyperinvariant tensor networks. Its tensor network description consists of local, non-perfect […]
Quantum 9, 1825 (2025). https://doi.org/10.22331/q-2025-08-08-1825 The rapid advancement of quantum hardware necessitates the development of reliable methods to certify its correct functioning. However, existing certification tests fall short, as they either suffer from systematic errors […]
D-Wave has announced its Q2 and first-half 2025 financial results. The table below summarizes key financial metrics for Q2 2025, with comparisons to the prior quarter (Q1 2025) and the year-ago quarter (Q2 2024). Amounts […]
IonQ has announced its Q2 and first-half 2025 financial results, highlighting revenue performance and strategic acquisitions. The table below summarizes key financial metrics for Q2 2025, with comparisons to the prior quarter (Q1 2025) and […]
Quantum 9, 1824 (2025). https://doi.org/10.22331/q-2025-08-08-1824 We present a theoretical proposal for preparing and manipulating a state of a single continuous-variable degree of freedom confined to a nonharmonic potential. By utilizing optimally controlled modulation of the […]
