quantum hardware

ETH Zurich researchers published a Nature paper demonstrating noise-resistant geometric-phase swap gates for neutral-atom qubits, achieving 99.91% fidelity simultaneously across 17,000 qubit pairs in under a millisecond.

DARPA's Heterogeneous Architectures for Quantum program will fund 19 teams over 24 months to combine different qubit types into unified quantum systems, abandoning the single-technology approach.
