Asymmetric One-Sided Semi-Device-Independent Steerability of Quantum Discordant States
Chellasamy Jebarathinam, Debarshi Das, R. Srikanth
Superlocality and superunsteerability provide operational characterization of quantum correlations in certain local and unsteerable states respectively. Such quantum correlated sta…
Testing Whether Gravity Acts as a Quantum Entity When Measured
Farhan Hanif, Debarshi Das, Jonathan Halliwell +4
A defining signature of classical systems is "in principle measurability" without disturbance: a feature manifestly violated by quantum systems. We describe a multi-interferometer…
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…
Quantum communication using a quantum switch of quantum switches
Debarshi Das, Somshubhro Bandyopadhyay
The quantum switch describes a quantum operation in which two or more quantum channels act on a quantum system with the order of application determined by the state of an order qua…
