Incompleteness is necessary for activation of nonlocality without entanglement
Atanu Bhunia, Saronath Halder, Preeti Parashar +1
A set of orthogonal product states is said to exhibit "quantum nonlocality without entanglement" if it is locally indistinguishable, i.e. no sequence of local operations and classi…
The likelihood operator and Fisher information in quantum probability
Kalyan B. Sinha, Ritabrata Sengupta
We study the problem of Quantum Likelihood Operators (LO) and their connection with quantum Fisher information (QFI). It is observed that the present approaches to this problem tac…
Infinite dimensional dynamical maps
Bihalan Bhattacharya, Uwe Franz, Saikat Patra +1
Completely positive trace preserving maps are widely used in quantum information theory. These are mostly studied using the master equation perspective. A central part in this theo…
Useful variants and perturbations of completely entangled subspaces and spans of unextendible product bases
Ritabrata Sengupta, Ajit Iqbal Singh
Finite dimensional entanglement for pure states has been used extensively in quantum information theory. Depending on the tensor product structure, even set of separable states can…
Generating random Gaussian states
Leevi Leppäjärvi, Ion Nechita, Ritabrata Sengupta
We develop a method for the random sampling of (multimode) Gaussian states in terms of their covariance matrix, which we refer to as a random quantum covariance matrix (RQCM). We a…
