Characterizing pairwise swapping capabilities of dense coding channels
Abhishek Muhuri, Nirman Ganguly, Aditi Sen De +1
We introduce a novel multipartite entanglement-assisted classical communication task, referred to as dense coding swapping, in which legitimate parties collaboratively swap the den…
Security of deterministic key distribution with higher-dimensional systems
Abhishek Muhuri, Ayan Patra, Rivu Gupta +2
We analyze the security of two-way quantum key distribution using arbitrary finite-dimensional systems, considering both individual and collective eavesdropping attacks, without th…
Probing non-equilibrium physics through the two-body Bell correlator
Abhishek Muhuri, Tanoy Kanti Konar, Leela Ganesh Chandra Lakkaraju +1
Identifying equilibrium criticalities and phases from the dynamics of a system, known as a dynamical quantum phase transition (DQPT), is a challenging task when relying solely on l…
Information theoretic resource-breaking channels
Abhishek Muhuri, Ayan Patra, Rivu Gupta +1
We propose the notion of process resource-breaking channels that break the resource for a quantum information processing task. We examine the same using quantum dense coding and te…
