Generating continuous variable entangled states for quantum teleportation using a superposition of number-conserving operations
Himadri Shekhar Dhar, Arpita Chatterjee, Rupamanjari Ghosh
We investigate the states generated in continuous variable (CV) optical fields on operating them with a number-conserving operator of the type $s\hat{a}\hat{a}^†+ t\hat{a}^†\hat{a}…
Cumulative quantum work-deficit versus entanglement in the dynamics of an infinite spin chain
Himadri Shekhar Dhar, Rupamanjari Ghosh, Aditi Sen De +1
We find that the dynamical phase transition (DPT) in nearest-neighbor bipartite entanglement of time-evolved states of the anisotropic infinite quantum XY spin chain, in a transver…
Patterns of Genuine Multipartite Entanglement in Frustrated Quantum Spin Systems
Lavisha Jindal, Ameya Deepak Rane, Himadri Shekhar Dhar +2
We investigate the behavior of genuine multipartite entanglement of paradigmatic frustrated quantum spin systems. We consider six different spin models, whose frustration ranges fr…
