Protocols for sharing genuine multipartite entanglement by employing copies of biseparable states
Swati Choudhary, Ujjwal Sen, Saronath Halder
Sharing genuine multipartite entanglement by considering collective use of copies of biseparable states, which are entangled across all bipartitions but lack genuine multipartite e…
Maximum entropy principle for quantum processes
Siddhartha Das, Ujjwal Sen
The maximum entropy principle, as applied to quantum systems, is a fundamental prescript positing that for a quantum system for which we only have partial knowledge, the maximum en…
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…
The Einstein-Podolsky-Rosen paradox and the Bell theorem
Ujjwal Sen
We will discuss here the Bell theorem, which shows that "locality" and "reality" are together inconsistent with quantum theory.
Stronger resilience to disorder in 2D quantum walks than in 1D
Amrita Mandal, Ujjwal Sen
We study the response of spreading behavior, of two-dimensional discrete-time quantum walks, to glassy disorder in the jump length. We consider different discrete probability distr…
To share and not share a singlet: control qubit and nonclassicality in teleportation
Kornikar Sen, Adithi Ajith, Saronath Halder +1
The superposition principle provides us the opportunity to unfold many surprising facts. One such fact leads to the generation of entanglement which may allow one to teleport an un…
