Strong subadditivity inequality for quantum entropies and four-particle entanglement
Asoka Biswas, G. S. Agarwal
Strong subadditivity inequality for a three-particle composite system is an important inequality in quantum information theory which can be studied via a four-particle entangled st…

Transfer of an unknown quantum state, quantum networks, and memory
Asoka Biswas, G. S. Agarwal
We present a protocol for transfer of an unknown quantum state. The protocol is based on a two-mode cavity interacting dispersively in a sequential manner with three-level atoms in…
