Quantum Zeno effect and nonclassicality in a PT symmetric system of coupled cavities
Javid Naikoo, Kishore Thapliyal, Subhashish Banerjee +1
The interplay between the nonclassical features and the parity-time (PT) symmetry (or its breaking) is studied here by considering a PT symmetric system consisting of two cavities…
Lower- and higher-order nonclassical properties of photon added and subtracted displaced Fock states
Priya Malpani, Nasir Alam, Kishore Thapliyal +3
Nonclassical properties of photon added and subtracted displaced Fock states have been studied using various witnesses of lower- and higher-order nonclassicality. Compact analytic…
Analysis of Quantum Key Distribution based Satellite Communication
Vishal Sharma, Subhashish Banerjee
Quantum key distribution is an effective encryption technique which can be used to perform secure quantum communication between satellite and ground stations. Quantum cryptography…
Effect of memory on the violation of Leggett-Garg inequality
Javid Naikoo, Subhashish Banerjee, R. Srikanth
The Leggett-Garg inequalities impose restrictions on the values taken by some combinations of the two-time correlation functions of observables in order to be explainable by a noni…
Non-Markovian dephasing and depolarizing channels
U. Shrikant, R. Srikanth, Subhashish Banerjee
We introduce a method to construct non-Markovian variants of completely positive (CP) dynamical maps, particularly, qubit Pauli channels. We identify non-Markovianity with the brea…
Enhanced non-Markovian behavior in quantum walks with Markovian disorder
N. Pradeep Kumar, Subhashish Banerjee, C. M. Chandrashekar
Non-Markovian quantum effects are typically observed in systems interacting with structured reservoirs. Discrete-time quantum walks are prime example of such systems in which, quan…
