Rigetti made its 108-qubit Cepheus-1-108Q generally available on both Quantum Cloud Services and Amazon Braket — the system uses a chiplet-based modular design and hits 99.1% median two-qubit gate fidelity at 60ns gate speed, tripling the qubit count from the prior generation. Researchers at Quantum Art in Israel published a new trapped-ion approach that drives all motional modes of an ion crystal simultaneously, letting a small set of global and semi-global pulses produce any multi-qubit gate without single-ion addressing hardware. IQM and Fraunhofer FOKUS pushed Qrisp to version 0.8, which produced the first concrete gate-level compilation of Shor's algorithm for 2048-bit RSA factoring — previous estimates were theoretical; this one has an exact qubit budget. And a team at NTNU developed a method to measure superconducting qubit coherence time roughly 100x faster than before, cutting measurement latency from ~1 second to ~10ms and making real-time error diagnostics viable.
