Toshiba Europe Achieves Long-Distance Quantum Communication Over 254 Kilometers
1. What Happened? Toshiba’s team conducted a groundbreaking trial in Germany, demonstrating the feasibility of coherent quantum communication over an extended range using existing fiber-optic networks. Notably, the system operated without the need for complex and costly cryogenic cooling equipment, relying instead on room-temperature semiconductor-based detectors. This approach significantly reduces the infrastructure requirements and costs…
