- Scientists just sent unhackable quantum keys across 120 kilometers
Scientists demonstrated a stable quantum encryption system across 120 kilometers of optical fiber, achieving high secure key rates and continuous operation for over six hours. The system uses tiny semiconductor quantum dots to emit single particles of light on demand. This breakthrough takes a major step toward ultra-secure quantum communication.
