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)…
Emergence of a new symmetry class for Bogoliubov-de Gennes (BdG) Hamiltonians: Expanding ten-fold symmetry classes
Ranjith Kumar R, Sujit Sarkar
Symmetry plays an important role in the topological states of quantum matter. Cartan found three symmetry classes, Altland and Zirnbauer extended it to the ten-fold symmetry class…
A Study of Curvature Theory for Different Symmetry Classes of Hamiltonian
Y R Kartik, Ranjith R Kumar, S Rahul +1
We study and present the results of curvature for different symmetry classes (BDI, AIII and A) model Hamiltonians and also present the transformation of model Hamiltonian from one…
Quantum Berezinskii-Kosterltz-Thouless Transition for Topological Insulator
Ranjith Kumar R, Rahul S, Surya Narayan +1
We consider the interacting helical liquid system at the one-dimensional edge of a two-dimensional topological insulator, coupled to an external magnetic field and s-wave supercond…
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…
An Interplay of Topology and Quantized Geometric Phase for two Different Symmetry-Class Hamiltonians
Rahul S, Ranjith Kumar R, Y R Kartik +2
Study of symmetry, topology and geometric phase can reveal many new and interesting results on the topological states of matter. Here we present a completely new and interesting re…
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…
