Non-Markovian noise limits for sustaining entanglement in multiparty quantum states
Suchetana Goswami, Ujjwal Sen
The principal resource in several quantum information processing tasks is entanglement. Building practically useful versions of such tasks, one often needs to consider multipartite…

What and why of entanglement
Ujjwal Sen
We present here a brief discussion, in Bangla (Bengali), on what is entanglement and why it is interesting.

Unconditionally superposition-robust entangled state in all multiparty quantum systems
Swati Choudhary, Ujjwal Sen, Saronath Halder
We investigate the inseparability of states generated by superposition of a multipartite pure entangled state with a product state. In particular, we identify specific multipartite…
