Quantum phase transitions of the Dirac oscillator in a minimal length scenario
L. Menculini, O. Panella, P. Roy
We obtain exact solutions of the (2+1) dimensional Dirac oscillator in a homogeneous magnetic field within a minimal length (), or generalised uncertainty princi…
Role of complementary correlations in the evolution of classical and quantum correlations under Markovian decoherence
Prasenjit Deb, Manik Banik
Quantum correlation lies at the very heart of almost all the non-classical phenomena exhibited by quantum systems composed of more than one subsystem. In the recent days it has bee…
All-versus-nothing violation of local realism from the Hardy paradox under no-signaling
Some Sankar Bhattacharya, Arup Roy, Amit Mukherjee +1
Hardy's is one of the simplest arguments concerning non-locality. Recently Chen et. al. have proposed a more generalized Hardy-like argument and have shown that the probability of…
Optimal quantum tomography with constrained elementary measurements arising from unitary bases
S. Chaturvedi, Sibasish Ghosh, K. R. Parthasarathy +1
The purpose of this paper is to introduce techniques of obtaining optimal ways to determine a d-level quantum state or distinguish such states. It entails designing constrained ele…
Entanglement properties of positive operators with ranges in completely entangled subspaces
R Sengupta, Arvind, Ajit Iqbal Singh
We prove that the projection on a completely entangled subspace S of maximum dimension in a multipartite quantum system obtained by Parthasarathy is not positive under partial tran…
Wigner-Yanase skew information and entanglement generation in quantum measurement
Manik Banik, Prasenjit Deb, Samyadeb Bhattacharya
The first step of quantum measurement procedure is known as \emph{premeasurement}, during when correlation between measuring system and measurement apparatus is established. One co…
