Mass-Independent Scheme to Test the Quantumness of a Massive Object
Debarshi Das, Dipankar Home, Hendrik Ulbricht +1
The search for empirical schemes to evidence the nonclassicality of large masses is a central quest of current research. However, practical schemes to witness the irreducible quant…
Measurement incompatibility and quantum advantage in communication
Debashis Saha, Debarshi Das, Arun Kumar Das +2
Measurement incompatibility stipulates the existence of quantum measurements that cannot be carried out simultaneously on single systems. We show that the set of input-output proba…
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…
