Decoherence can help quantum cryptographic security
Vishal Sharma, U. Shrikant, R. Srikanth +1
In quantum key distribution, one conservatively assumes that the eavesdropper Eve is restricted only by physical laws, whereas the legitimate parties, namely the sender Alice and r…
Non-Markovian evolution: a quantum walk perspective
Pradeep Kumar, Subhashish Banerjee, R. Srikanth +2
Quantum non-Markovianity of a quantum noisy channel manifests typically as information backflow, characterized by the departure of the intermediate map from complete positivity, th…
Quantum bit commitment and the reality of the quantum state
R. Srikanth
Quantum bit commitment (QBC) is insecure in the standard non-relativistic quantum cryptographic framework, essentially because Alice can exploit quantum steering to defer making he…
A Study of Topological Quantum Phase Transition and Majorana Localization Length for the Interacting Helical Liquid System
Dayasindhu Dey, Sudip Kumar Saha, P. Singha Deo +2
We consider a helical spin liquid system which shows majorana fermion modes at the edge. The interaction between the quasiparticles in this system induces phase transition, Majoran…
Operational characterization of quantumness of unsteerable bipartite states
Debarshi Das, Bihalan Bhattacharya, Chandan Datta +4
Recently, the quantumness of local correlations arising from separable states in the context of a Bell scenario has been studied and linked with superlocality [Phys. Rev. A {\bf 95…
Operational nonclassicality of local multipartite correlations in the limited-dimensional simulation scenario
C. Jebaratnam, Debarshi Das, Suchetana Goswami +2
For a bipartite local quantum correlation, superlocality refers to the requirement for a larger dimension of the random variable in the classical simulation protocol than that of t…
