Superunsteerability as a quantifiable resource for random access codes assisted by Bell-diagonal states
C. Jebarathinam, Debarshi Das, Som Kanjilal +4
We show how nonclassical correlations in local bipartite states can act as a resource for quantum information processing. Considering the task of quantum random access codes (RAC)…
Hierarchical axioms for quantum mechanics
S. Aravinda, Anirban Pathak, R. Srikanth
The origin of nonclassicality in quantum mechanics (QM) has been investigated recently by a number of authors with a view to identifying axioms that would single out quantum mechan…
Effect of memory on the violation of Leggett-Garg inequality
Javid Naikoo, Subhashish Banerjee, R. Srikanth
The Leggett-Garg inequalities impose restrictions on the values taken by some combinations of the two-time correlation functions of observables in order to be explainable by a noni…
Non-Markovian dephasing and depolarizing channels
U. Shrikant, R. Srikanth, Subhashish Banerjee
We introduce a method to construct non-Markovian variants of completely positive (CP) dynamical maps, particularly, qubit Pauli channels. We identify non-Markovianity with the brea…
Path integral approach to one-dimensional discrete-time quantum walk
Karthik S. Joshi, S. K. Srivatsa, R. Srikanth
Discrete-time quantum walk in one-dimension is studied from a path-integral perspective. This enables derivation of a closed-form expression for amplitudes corresponding to any coi…
Quantum cryptography: key distribution and beyond
Akshata Shenoy H., Anirban Pathak, R. Srikanth
Uniquely among the sciences, quantum cryptography has driven both foundational research as well as practical real-life applications. We review the progress of quantum cryptography…
Maximally nonlocal subspaces
Akshata Shenoy H., R. Srikanth
A nonlocal subspace is a subspace within the Hilbert space of a multi-particle system such that every state violates a gi…
