Quantum coherence via conditional entropy

2018 · Journal of Physics A Mathematical and Theoretical

Abstract Quantum coherence characterizes the non-classical feature of a single party system with respect to a local basis. Based on a recently introduced resource framework, coherence can be regarded as a resource and be systematically …

Quantifying Coherence with Untrusted Devices

2018 · arXiv (Cornell University)

Device-independent (DI) tests allow to witness and quantify the quantum feature of a system, such as entanglement, without trusting the implementation devices. Although DI test is a powerful tool in many quantum information tasks, it …
