A narrow constriction in the chip's superconducting film — the same Josephson-junction element already there — acts as a passive millikelvin thermometer, freeing chip debugging from microwave-based qubit thermometry.
A programmable ultraviolet projector, tracking the spinning crystal of a Penning trap (a magnetic bottle for charged atoms), can steer more than 100 trapped ions locally.
A live audio-video VPN stayed encrypted for eight continuous hours using quantum-physics keys delivered through ETSI's QKD 014 standard. The protocol works; the hardware still runs on one vendor.
Luxquanta and three fellow small and mid-sized enterprises (Quside, Chilas, fragmentiX) lead the EU's European Quantum Communication Infrastructure (EuroQCI) quantum-communications infrastructure programme alongside infrastructure partner
CSIRO, Australia's national science agency, delivered portable entangled-photon hardware to back up GPS for the military, and any sign of interception collapses the channel that carries the timing.
The French-cleared deal pairs BTQ's post-quantum security protocols with a 100+ qubit emulator, letting defense and telecom buyers test cryptography before quantum computers arrive.
Oratomic will build quantum bits from individual atoms held in focused laser "optical tweezers" rather than superconducting chips. The architecture lets qubits rearrange to match an error-correcting code.
A constraint-preserving mixing strategy called an XY-mixer — which enforces the one-guide-per-gene rule structurally in a quantum circuit, bypassing tunable penalty terms — beats three penalty-tuned variants in simulation and holds up better on
