An almost convincing scheme for discriminating the preparation basis of quantum ensemble and why it will not work
Sandeep K Goyal, Rajeev Singh, Sibasish Ghosh
Mixed states of a quantum system, represented by density operators, can be decomposed as a statistical mixture of pure states in a number of ways where each decomposition can be vi…
Reciprocal ontological models show indeterminism of the order of quantum theory
Somshubhro Bandyopadhyay, Manik Banik, Some Sankar Bhattacharya +4
The question whether indeterminism in quantum measurement outcomes is fundamental or is there a possibility of constructing a finer theory underlying quantum mechanics that allows…
On witnessing arbitrary bipartite entanglement in a measurement device independent way
Arindam Mallick, Sibasish Ghosh
Experimental detection of entanglement of an arbitrary state of a given bipartite system is crucial for exploring many areas of quantum information. But such a detection should be…
Necessary Condition for Local Distinguishability of Maximally Entangled States: Beyond Orthogonality Preservation
Tanmay Singal, Ramij Rahman, Sibasish Ghosh +1
The (im)possibility of local distinguishability of orthogonal multipartite quantum states still remains an intriguing question. Beyond , the pr…
Separability Criterion for Multi-Mode Gaussian States
K. V. S. Shiv Chaitanya, Sibasish Ghosh, V. Srinivasan
In this paper, we give Separability criterion for the multi-mode Gaussian states using the Marchenko-Pastur theorem. We show that the Marchenko-Pastur theorem from random matrix th…
