DOI: 10.1016/j.scib.2018.06.018

Abstract: Abstract Quantum nonlocality and quantum contextuality are the most curious properties that change our understanding of nature, and were observed independently in recent decades. One important question is whether both properties can be observed simultaneously.… read more here.

DOI: 10.1038/s41598-025-06140-4

Abstract: This study investigates the nonlocality characteristics of output states produced by a universal quantum cloning machine, with particular emphasis on the Bell-CHSH inequality violations exhibited by the two-qubit reduced states of cloned outputs. Through systematic… read more here.

DOI: 10.1103/bqwm-ll5y

Abstract: We discuss Bell nonlocality in quantum networks with unreliable sources. Our main result is a condition on the observed data that ensures that inconclusive events can be safely discarded, without introducing any loophole. More formally,… read more here.

DOI: 10.1103/physrevlett.130.220201

Abstract: Nonlocality, as established by seminal Bell's theorem, is considered to be the most striking feature of correlations present in space like separated events. Its practical application in device independent protocols, such as, secure key distribution,… read more here.
