Quantum Signals Sent Over Commercial Fiber Using Standard Internet Protocol

Researchers at the University of Pennsylvania have achieved a groundbreaking feat: transmitting quantum signals over commercial fiber-optic cables using the standard Internet Protocol (IP). Their innovative Q-chip coordinates quantum and classical data, packaging them into standard internet packets. This overcomes the fragility of quantum signals and represents a crucial step towards a practical quantum internet, promising faster, more energy-efficient AI and breakthroughs in drug and materials design.
