Sufficient conditions for quantum advantage in random access code protocols with two-qubit states
Som Kanjilal, C Jebarathinam, Tomasz Paterek +1
Random access code (RAC) is an important communication protocol to obtain information about a randomly specified substring of an n-bit string, while only having limited information…
Broadcasting of NPT Entanglement in Two Qutrit Systems
Rounak Mundra, Sabuj Chattopadhyay, Indranil Chakrabarty +1
It is known that beyond and dimensional quantum systems, Peres-Hordecki criterion is no longer sufficient as an entanglement detection criterion as ther…
Quantumness of Relative Incompatibility
Manish Kumar Shukla, Rounak Mundra, Arun K Pati +2
We propose a new measure of relative incompatibility for a quantum system with respect to two non-commuting observables, and call it quantumness of relative incompatibility. In cas…
Broadcasting of non-locality
Dhrumil Patel, Arup Roy, Indranil Chakrabarty +1
Bell nonlocality and steering are archetypal characteristics of quantum mechanics that mark a significant departure from conventional classical notions. They basically refer to the…
Nearly Markovian maps and entanglement-based bound on corresponding non-Markovianity
Sreetama Das, Sudipto Singha Roy, Samyadeb Bhattacharya +1
We identify a set of dynamical maps of open quantum system, and refer to them as "-Markovian" maps. It is constituted of maps which, in a higher dimensional system-environment…
Broadcasting of correlations via orthogonal & non-orthogonal state dependent cloners
Manish Kumar Shukla, Indranil Chakrabarty, Sourav Chatterjee
In this work, we extensively study the problem of broadcasting of entanglement as state dependent versus state independent cloners. We start by re-conceptualizing the idea of state…
Thermodynamic utility of Non-Markovianity from the perspective of resource interconversion
Samyadeb Bhattacharya, Bihalan Bhattacharya, A. S. Majumdar
We establish a connection between non-Markovianity and negative entropy production rate for various classes of quantum operations. We analyse several aspects of unital and thermal…
Detecting non-Markovianity via uncertainty relations
Ananda G. Maity, Samyadeb Bhattacharya, A. S. Majumdar
We present a formalism for detection of non-Markovianity through uncertainty relations. We show that when there is an information back-flow to the system from its environment throu…
