Enhancement of an Unruh-DeWitt battery performance through quadratic environmental coupling
Arnab Mukherjee, Sunandan Gangopadhyay, A. S. Majumdar
We investigate relativistic effects on the performance of a quantum battery in an open quantum framework. We consider an Unruh-DeWitt detector driven by a coherent classical pulse…
Nonlocality in Continuous-Variable Quantum Networks
Sudip Chakrabarty, Amit Kundu, A. S. Majumdar
Quantum networks enable forms of nonlocality beyond the standard Bell scenario, with a multitude of potential applications. Continuous-variable (CV) platforms are particularly attr…
Detection of nonabsolute separability in quantum states and channels through moments
Bivas Mallick, Saheli Mukherjee, Nirman Ganguly +1
In quantum information and computation, the generation of entanglement through unitary gates remains a significant and active area of research. However, there are states termed as…
Classifying Measurement Incompatibility under Classical Pre- and Post-Processing Operations
Arun Kumar Das, Saheli Mukherjee, Debashis Saha +2
Measurement incompatibility has proved to be an important resource for quantum information processing. In this work, we present an operational approach that leverages classical ope…
Device-Independent Anonymous Communication in Quantum Networks
Srijani Das, Manasi Patra, Tuhin Paul +2
Anonymity is a fundamental cryptographic primitive that hides the identities of both senders and receivers during message transmission over a network. Classical protocols cannot pr…
Detecting genuine multipartite entanglement using moments of positive maps
Saheli Mukherjee, Bivas Mallick, Sahil Gopalkrishna Naik +2
Genuine multipartite entanglement (GME) represents the strongest form of entanglement in multipartite systems, providing significant advantages in various quantum information proce…
