Quantum superposition of causal structures as a universal resource for local implementation of nonlocal quantum operations
Pratik Ghosal, Arkaprabha Ghosal, Debarshi Das +1
Spatial separation restricts the set of locally implementable quantum operations on distributed multipartite quantum systems. We propose that indefinite causal structure arising du…
Activating information backflow with the assistance of quantum SWITCH
Ananda G. Maity, Samyadeb Bhattacharya
There are certain dynamics while being non-Markovian, do never exhibit information backflow. We show that if two such dynamical maps are considered in a scenario where the order of…
Role of nonclassical temporal correlation in powering quantum random access codes
Subhankar Bera, Ananda G. Maity, Shiladitya Mal +1
We explore the fundamental origin of the quantum advantage behind random access code. We propose new temporal inequalities compatible with noninvasive-realist models and show that…
