Role of Bell-CHSH violation and local filtering in quantum key distribution
Jaskaran Singh, Sibasish Ghosh, Arvind +1
In this article, we analyse the relationship between the Bell violation and the secure key rate of entanglement assisted quantum key distribution (QKD) protocols. Specifically, we…
Coherence assisted non-Gaussian measurement device independent quantum key distribution
Chandan Kumar, Jaskaran Singh, Soumyakanti Bose +1
Non-Gaussian operations on two mode squeezed vacuum states (TMSV) in continuous variable measurement device independent quantum key distribution (CV-MDI-QKD) protocols have been sh…
Experimental demonstration of fully contextual quantum correlations on an NMR quantum information processor
Dileep Singh, Jaskaran Singh, Kavita Dorai +1
The existence of contextuality in quantum mechanics is a fundamental departure from the classical description of the world. Currently, the quest to identify scenarios which cannot…
On-demand quantum key distribution using superconducting rings with a mesoscopic Josephson junction
Chandan Kumar, Jaskaran Singh, Arvind
We present a quantum key distribution (QKD) protocol based on long lived coherent states prepared on superconducting rings with a mesoscopic Josephson junction (dc-SQUIDs). This en…
Authentication protocol based on collective quantum steering
Debasis Mondal, Chandan Datta, Jaskaran Singh +1
It is well known that certain quantum correlations like quantum steering exhibit a monogamous relationship. In this paper, we exploit the asymmetric nature of quantum steering and…
