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 quantumness-certification with linear functionals
Soumyakanti Bose, Yong-Siah Teo, Hyukjoon Kwon +1
Despite several approaches proposed to operationally characterize quantum states of light-those that cannot be sampled with a positive distribution over classical states-most exist…
