Nonclassical Preparation of Quantum Remote States

2020 · arXiv (Cornell University)

Remote state preparation (RSP) enables a sender to remotely prepare the quantum state of a receiver without sending the state itself. Recently, it has been recognized that quantum discord is a necessary resource for RSP. …

Detecting quantum non-breaking channels without entanglement

2021 · arXiv (Cornell University)

Quantum channels, which break entanglement, incompatibility, or nonlocality, are not useful for entanglement-based, one-sided device-independent, or device-independent quantum information processing, respectively. Here, we show that such breaking channels are related to certain temporal quantum correlations, …
