The Hardy's nonlocality argument
Sujit K Choudhary, Pankaj Agrawal
Certain predictions of quantum theory are not compatible with the notion of local-realism. This was the content of Bell's famous theorem of the year 1964. Bell proved this with the…
Quantum nonlocality via local contextuality with qubit-qubit entanglement
Debashis Saha, Adán Cabello, Sujit K. Choudhary +1
Quantum nonlocality can be revealed "via local contextuality" in qudit-qudit entangled systems with , that is, through the violation of inequalities containing Alice-Bob cor…
Process tomography via sequential measurements on a single quantum system
Humairah Bassa, Sandeep K. Goyal, Sujit K. Choudhary +3
We utilize a discrete (sequential) measurement protocol to investigate quantum process tomography of a single two-level quantum system, with an unknown initial state, undergoing Ra…
Measuring higher-dimensional entanglement
Chandan Datta, Pankaj Agrawal, Sujit K. Choudhary
We study local-realistic inequalities, Bell-type inequalities, for bipartite pure states of finite dimensional quantum systems -- qudits. There are a number of proposed Bell-type i…
Certifiable randomness from temporal correlations
Shiladitya Mal, Manik Banik, Sujit K Choudhary
Leggett-Garg inequalities (LGI) are constrains on certain combinations of temporal correlations obtained by measuring one and the same system at two different instants of time. The…
Ontological models, preparation contextuality and nonlocality
Manik Banik, Some Sankar Bhattacharya, Sujit K Choudhary +2
The ontological model framework for an operational theory has generated much interest in recent years. The debate concerning reality of quantum states has been made more precise in…
