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…
Locally unidentifiable subset of quantum states and its resourcefulness in secret password distribution
Pratik Ghosal, Arkaprabha Ghosal, Subhendu B. Ghosh +1
We introduce a hitherto unexplored form of quantum nonlocality, termed local subset unidentifiability, that arises from the limitation of spatially separated parties to perfectly i…
Probability distribution for black hole evaporation
Pratik Ghosal, Rajarshi Ray
Non-thermal correction to the emission probability of particles from black holes can be obtained if the backreaction or self-gravitational effects of the emitted particles on the b…
