Finite-energy Gottesman-Kitaev-Preskill state-enhanced optical interferometry

Ashmita Roy, R. Srikanth, Deepak Pandey

We present the case of a Gottesman-Kitaev-Preskill (GKP) state-enhanced optical interferometry with detailed analysis of the phase sensitivity for both the SU(2) and SU(1,1) interf…

Characterization of a damping channel as a mixture of amplitude damping and anti-damping channels of different parameters

Vijay Pathak, R. Srikanth

Non-unital noise is a fundamental feature of open quantum systems, governing energy exchange and inducing state translations on the Bloch sphere. While such translations can be use…

On the distinction between distinguishability of states and witness of non-Markovianity of dynamical maps

Vijay Pathak, R. Srikanth

Non-P-divisibility is the strongest divisibility-based notion of quantum non-Markovianity. The generalized trace distance (GTD) based criterion is known to be an optimal witness of…

Asymmetric One-Sided Semi-Device-Independent Steerability of Quantum Discordant States

Chellasamy Jebarathinam, Debarshi Das, R. Srikanth

Superlocality and superunsteerability provide operational characterization of quantum correlations in certain local and unsteerable states respectively. Such quantum correlated sta…

Experimental realization of quantum non-Markovianity through the convex mixing of Pauli semigroups on an NMR quantum processor

Vaishali Gulati, Vinayak Jagadish, R. Srikanth +1

This experimental study aims to investigate the convex combinations of Pauli semigroups with arbitrary mixing parameters to determine whether the resulting dynamical map exhibits M…

Noninvertibility and non-Markovianity of quantum dynamical maps

Vinayak Jagadish, R. Srikanth, Francesco Petruccione

We identify two broad types of noninvertibilities in quantum dynamical maps, one necessarily associated with CP indivisibility and one not so. We study the production of (non-)Mark…
