Nonclassical resource for continuous-variable telecloning with non-Gaussian advantage

|
By Sudipta Das, Rivu Gupta, A Ci, Chhatnag Road
| Physical Review B
The telecloning protocol distributes quantum states from a single sender to multiple receivers via a shared entangled state by exploiting the notions of teleportation and approximate cloning. We investigate the optimal telecloning fidelities obtained using both Gaussian and non-Gaussian shared resources.

Superiority in dense coding through non-Markovian stochasticity

|
By A Ci, Chhatnag Road, Rivu Gupta, Abhishek Muhuri
| Physical Review B
We investigate the distributed dense coding (DC) protocol, involving multiple senders and a single or two receivers under the influence of non-Markovian noise, acting on the encoded qubits transmitted from the senders to the receiver(s). We compare the effects of non-Markovianity on DC for both the dephasing and depolarizing channels.

Emergence of monogamy under static and dynamic scenarios

|
By Rivu Gupta, Chhatnag Road, Saptarshi Roy, Shiladitya Mal
| Physical Review B
Abstract Characterizing multipartite quantum correlations beyond two parties is of utmost importance for building cutting edge quantum technologies, although the comprehensive picture is still missing. Here we investigate quantum correlations (QCs) present in a multipartite system by exploring connections between magentathree different frameworks, namely, the monogamy score (MS), localizable quantum correlations (LQC), and genuine multipartite entanglement (GME) content of the state.
