Detecting entanglement harnessing Lindblad structure
Vaibhav Chimalgi, Bihalan Bhattacharya, Suchetana Goswami +1
The problem of entanglement detection is a long standing problem in quantum information theory. One of the primary procedures of detecting entanglement is to find the suitable posi…
Revisiting the quantum open system dynamics of central spin model
Samyadeb Bhattacharya, Subhashish Banerjee
In this article we revisit the theory of open quantum systems from the perspective of fermionic baths. Specifically, we concentrate on the dynamics of a central spin half particle…
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…
Convex geometry of Markovian Lindblad dynamics and witnessing non-Markovianity
Bihalan Bhattacharya, Samyadeb Bhattacharya
We develop a theory of linear witnesses for detecting non-Markovianity, based on the geometric structure of the set of Choi states for all Markovian evolutions having Lindblad type…
Convex resource theory of non-Markovianity
Samyadeb Bhattacharya, Bihalan Bhattacharya, A. S. Majumdar
We establish a convex resource theory of non-Markovianity under the constraint of small time intervals within the temporal evolution. We construct the free operations, free states…
