Maximum tri-partite Hardy's nonlocality respecting all bi-partite principles
Subhadipa Das, Manik Banik, M. D. Rajjak Gazi +3
The set of multiparty correlations that respect all bi-partite principles has been conjectured to be same as the set of time-ordered-bi-local correlations. Based on this conjunctur…
Uncertainty principle certifies genuine source of intrinsic randomness
Trina Chakraborty, Manik Banik, Pinaki Patra
The Born's rule introduces intrinsic randomness to the outcomes of a measurement performed on a quantum mechanical system. But, if the system is prepared in the eigenstate of an ob…
Hartman effect and dissipative quantum systems
Samyadeb Bhattacharya, Sisir Roy
The dwell time for dissipative quantum system is shown to increase with barrier width. It clearly precludes Hartman effect for dissipative systems. Here calculation has been done f…
Hardy's nonlocality argument as witness for post-quantum correlation
Subhadipa Das, Manik Banik, Ashutosh Rai +2
Recently, Gallego et.al. [Phys. Rev. Lett 107, 210403 (2011)] proved that any future information principle aiming at distinguishing between quantum and post-quantum correlation mus…
Weak value of Dwell time for Quantum Dissipative spin-1/2 System
Samyadeb Bhattacharya, Sisir Roy
The dwell time is calculated within the framework of time dependent weak measurement considering dissipative interaction between a spin half system and the environment. Caldirola a…
Entanglement is not a lower bound for geometric discord
Swapan Rana, Preeti Parashar
We show that partial transposition of any state can have at most number of negative eigenvalues. This extends a decade old result of case by Sanpe…
Geometric discord and Measurement-induced nonlocality for well known bound entangled states
Swapan Rana, Preeti Parashar
We employ geometric discord and measurement induced nonlocality to quantify non classical correlations of some well-known bipartite bound entangled states, namely the two families…
Degree of Complementarity Determines the Nonlocality in Quantum Mechanics
Manik Banik, M. D. Rajjak Gazi, Sibasish Ghosh +1
Complementarity principle is one of the central concepts in quantum mechanics which restricts joint measurement for certain observables. Of course, later development shows that joi…
Quantum Ternary Circuit Synthesis Using Projection Operations
Sudhindu Bikash Mandal, Amlan Chakrabarti, Susmita Sur-Kolay
Basic logic gates and their operations in ternary quantum domain are involved in the synthesis of ternary quantum circuits. Only a few works define ternary algebra for ternary quan…
Eavesdropping in Semiquantum Key Distribution Protocol
Arpita Maitra, Goutam Paul
In semiquantum key-distribution (Boyer et al.) Alice has the same capability as in BB84 protocol, but Bob can measure and prepare qubits only in basis an…
Local simulation of singlet statistics for restricted set of measurement
Ashutosh Rai, MD. Rajjak Gazi, Manik Banik +2
The essence of Bell's theorem is that, in general, quantum statistics cannot be reproduced by local hidden variable (LHV) model. This impossibility is strongly manifested while ana…
Optimal free-will on one side in reproducing the singlet correlation
Manik Banik, MD Rajjak Gazi, Subhadipa Das +2
Bell's theorem teaches us that there are quantum correlations that can not be simulated by just shared randomness (Local Hidden variable). There are some recent results which simul…
Classical communication and non-classical fidelity of quantum teleportation
Manik Banik, Md. Rajjak Gazi
In quantum teleportation, the role of entanglement has been much discussed. It is known that entanglement is necessary for achieving non-classical teleportation fidelity. Here we f…
Tight lower bound on geometric discord of bipartite states
Swapan Rana, Preeti Parashar
We use singular value decomposition to derive a tight lower bound for geometric discord of arbitrary bipartite states. In a single shot this also leads to an upper bound of measure…
