Coherence of quantum channels
Chandan Datta, Sk Sazim, Arun K. Pati +1
We investigate the coherence of quantum channels using the Choi-Jamiołkowski isomorphism. The relation between the coherence and the purity of the channel respects a duality relati…
Operational characterization of quantumness of unsteerable bipartite states
Debarshi Das, Bihalan Bhattacharya, Chandan Datta +4
Recently, the quantumness of local correlations arising from separable states in the context of a Bell scenario has been studied and linked with superlocality [Phys. Rev. A {\bf 95…
Distinguishing different classes of entanglement of three-qubit pure states
Chandan Datta, Satyabrata Adhikari, Arpan Das +1
Employing the Pauli matrices, we have constructed a set of operators, which can be used to distinguish six inequivalent classes of entanglement under SLOCC (stochastic local operat…
Super Rogers-Szegö polynomials associated with type of Polychronakos spin chains
B. Basu-Mallick, C. Datta
As is well known, multivariate Rogers-Szegö polynomials are closely connected with the partition functions of the type of Polychronakos spin chains having long-range inte…
