Phase boundaries in alternating field quantum XY model with Dzyaloshinskii-Moriya interaction: Sustainable entanglement in dynamics
Saptarshi Roy, Titas Chanda, Tamoghna Das +3
We report all phases and corresponding critical lines of the quantum anisotropic transverse XY model with Dzyaloshinskii-Moriya (DM) interaction along with uniform and alternating…
Deterministic Quantum Dense Coding Networks
Saptarshi Roy, Titas Chanda, Tamoghna Das +2
We consider the scenario of deterministic classical information transmission between multiple senders and a single receiver, when they a priori share a multipartite quantum state -…
Emergence of entanglement with temperature and time in factorization-surface states
Titas Chanda, Tamoghna Das, Debasis Sadhukhan +3
There exist zero-temperature states in quantum many-body systems that are fully factorized, thereby possessing vanishing entanglement, and hence being of no use as resource in quan…
Quantum discord and its allies: a review
Anindita Bera, Tamoghna Das, Debasis Sadhukhan +3
We review concepts and methods associated with quantum discord and related topics. We also describe their possible connections with other aspects of quantum information and beyond,…
