Quantum information scrambling (QIS) describes the rapid spread of initially localized information across an entire quantum many-body system through entanglement generation. Once s…
Efficient Detection of Preparing Quantum Remote States Using Coherence Quantum Benefits
Yuan-Sung Liu, Shih-Hsuan Chen, Bing-Yuan Lee +4
A sender can prepare a quantum state for a remote receiver using preshared entangled pairs, only the sender's single-qubit measurement, and the receiver's simple correction informe…
