Entanglement Purification and Protection in a Superconducting Quantum Network

Entanglement Purification and Protection in a Superconducting Quantum Network High-fidelity quantum entanglement is a key resource for quantum communication and distributed quantum computing, enabling quantum state teleportation, dense coding, and quantum encryption. Any sources of decoherence in the communication channel, however, degrade entanglement fidelity, thereby increasing the error rates of entangled state protocols. Entanglement purification provides a method to alleviate these nonide...
