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…
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…
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…
