Loophole-free Bell-inequality violation between atomic states in cavity-QED systems mediated by hybrid atom-light entanglement
Pei-Zhe Li, Soumyakanti Bose, Hyunseok Jeong +3
We present a feasible and scalable approach to testing Bell nonlocality and implementing device-independent quantum key distribution (DI-QKD) between distant atomic states in cavit…

No-Go Theorem for Norm-Based Nonclassicality Certification with Linear Functionals
Soumyakanti Bose, Yong-Siah Teo, Hyukjoon Kwon +1
Despite various approaches to encode nonclassical light, most existing formulations either suffer from limited practicality or rely on optimization procedures that are computationa…
