Concatenating quantum error-correcting codes with decoherence-free subspaces and vice versa

Nihar Ranjan Dash, Sanjoy Dutta, R. Srikanth +1

Quantum error-correcting codes (QECCs) and decoherence-free subspace (DFS) codes provide active and passive means, respectively, to address certain types of errors that arise durin…

Protocols for counterfactual and twin-field quantum digital signature

Vinod N. Rao, Shrikant Utagi, Anirban Pathak +1

Quantum digital signature (QDS) is the quantum version of its classical counterpart, and can offer security against attacks of repudiation, signature forging and external eavesdrop…

Unconventional quantum criticality in a non-Hermitian extended Kitaev chain

S Rahul, Nilanjan Roy, Ranjith R Kumar +2

We investigate the nature of quantum criticality and topological phase transitions near the critical lines obtained for the extended Kitaev chain with next nearest neighbor hopping…

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…

Experimental realization of quantum non-Markovianity through the convex mixing of Pauli semigroups on an NMR quantum processor

Vaishali Gulati, Vinayak Jagadish, R. Srikanth +1

This experimental study aims to investigate the convex combinations of Pauli semigroups with arbitrary mixing parameters to determine whether the resulting dynamical map exhibits M…

Noninvertibility and non-Markovianity of quantum dynamical maps

Vinayak Jagadish, R. Srikanth, Francesco Petruccione

We identify two broad types of noninvertibilities in quantum dynamical maps, one necessarily associated with CP indivisibility and one not so. We study the production of (non-)Mark…
