Experimental measurement-device-independent high dimensional entanglement quantification

2019 · arXiv (Cornell University)

The certification and quantification of entanglement are of great importance in characterizing entangled systems. Measurement-device-independent entanglement witness (MDIEW) has been developed to solve the problem of imperfection of measurement schemes and has been used to …

Experimental realization of high-fidelity teleportation via a non-Markovian open quantum system

2020 · Physical Review A

Open quantum systems and study of decoherence are important for our fundamental understanding of quantum physical phenomena. For practical purposes, a large number of quantum protocols exist that exploit quantum resources, e.g., entanglement, which allows …

Experimental beating the standard quantum limit under non-markovian dephasing environment

2022 · arXiv (Cornell University)

Entanglement enhanced quantum metrology has been well investigated for beating the standard quantum limit (SQL). However, the metrological advantage of entangled states becomes much more elusive in the presence of noise. Under strictly Markovian dephasing …

Certification of genuinely entangled subspaces of the five qubit code via robust self-testing

2025 · Reports on Progress in Physics

Self-testing provides a device-independent framework for certifying quantum properties based solely on input-output statistics while treating quantum devices as black boxes. It has evolved significantly from its origins in bipartite systems to applications in multipartite …
