The UK Space Agency and DSIT have published a Quantum Technology Roadmap for Space, outlining strategic priorities for 2035–2040. The roadmap identifies four investment themes: assured timing, resilient sensing, sovereign communications, and long-term computing, aiming to transition prototypes into flight-qualified space systems. It also emphasizes the need to address engineering…
Pasqal's 256-qubit neutral-atom processor observed an unexpected slowdown in a 2D quantum magnet's dynamics, diverging from classical simulations. This research, detailed in a preprint, explores the relaxation landscape of a 2D transverse-field Ising model, uncovering three distinct physical behaviors including a previously unpredicted relaxation slowdown at intermediate field strengths. The…
BlueQubit, in collaboration with EPFL and the XPRIZE Foundation, has demonstrated quantum computational advantage using IBM Quantum's 120-qubit ibm_phoenix processor. Their random-circuit sampling experiment, involving 61 active qubits, achieved a fidelity that would take over a century for classical supercomputers to replicate. This study highlights significant architectural improvements in IBM…
