Quantum dice: Scientists harness true randomness from entangled photons
Scientists at NIST and the University of Colorado Boulder have created CURBy, a cutting-edge quantum randomness beacon that draws on the intrinsic unpredictability of quantum entanglement to produce true random numbers. Unlike traditional methods, CURBy is traceable, transparent, and verifiable…
Quantum breakthrough: ‘Magic states’ now easier, faster, and way less noisy
Quantum computing just got a significant boost thanks to researchers at the University of Osaka, who developed a much more efficient way to create “magic states”—a key component for fault-tolerant quantum computers. By pioneering a low-level, or “level-zero,” distillation method,…
Scientists create ‘universal translator’ for quantum tech
Scientists at UBC have devised a chip-based device that acts as a “universal translator” for quantum computers, converting delicate microwave signals to optical ones and back with minimal loss and noise. This innovation preserves crucial quantum entanglement and works both…
