IBM says quantum computers now outperform classical systems with verifiable results

IBM International Business Machines Corporation announced on Thursday that quantum computers have reached a stage where they can perform calculations beyond the practical reach of classical systems while simultaneously providing trustworthy, verifiable results — a milestone the company calls "quantum…

Two labs achieve steady-state qubit entanglement independently

Two research groups working on opposite sides of the Atlantic have independently demonstrated a way to keep physically separated qubits continuously entangled without the precisely timed control pulses that typically make remote entanglement an engineering bottleneck. The parallel results, published…
