Thin-Film Quantum Photonic Technologies for Quantum Teleportation
Abstract: One of the most important protocols in distributed quantum computing and quantum communication is quantum teleportation, which allows quantum information to be sent between distant nodes without actually sending the quantum particle. The teleportation process is fundamentally based on quantum entanglement, Bell state measurements, and classical communication channels, which collectively allow the accurate reconstruction of an unknown quantum state at a remote location. In recent years, rapid progress in integrated …
