Absolute Non-Violation of a Three-Setting Steering Inequality by Two-Qubit States
Some Sankar Bhattacharya, Amit Mukherjee, Arup Roy +5
Steerability is a characteristic nonlocal trait of quantum states lying in between entanglement and Bell nonlocality. A given quantum state is considered to be steerable if it viol…
Bell-CHSH Violation Under Global Unitary Operations: Necessary and Sufficient conditions
Nirman Ganguly, Amit Mukherjee, Arup Roy +3
The relation between Bell-CHSH violation and factorization of Hilbert space is considered here. That is, a state which is local in the sense of the Bell-CHSH inequality under a cer…
Persistency of Genuine Correlations Under Particle Loss
Biswajit Paul, Kaushiki Mukherjee, Ajoy Sen +4
In a recent work [\href{http://journals.aps.org/pra/abstract/10.1103/PhysRevA.86.042113}{Phys. Rev. A 86, 042113 (2012)}] the question of persistency of entanglement and nonlocalit…
Conditional steering under von-Neumann scenario
Kaushiki Mukherjee, Biswajit Paul, Sumana Karmakar +4
In [\href{http://www.sciencedirect.com/science/article/pii/037596019290711T}{Phys. Lett. A {\bf 166}, 293 (1992)}] Popescu characterized nonlocality of pure -partite entangled s…
Characterization of Nonlocal Resources Under Global Unitary Action
Arup Roy, Some Sankar Bhattacharya, Amit Mukherjee +1
The task of device independent secure key distribution requires preparation and subsequently distribution of nonlocal resources. For secured practical implementation, one needs to…
The presence of quantum correlations result in non-vanishing ergotropic gap
Amit Mukherjee, Arup Roy, Some Sankar Bhattacharya +1
The paradigm of extracting work from isolated quantum system through a cyclic Hamiltonian process is a topic of immense research interest. The optimal work extracted under such pro…
