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…
Higher-dimensional entanglement detection and quantum channel characterization using moments of generalized positive maps
Bivas Mallick, Ananda G. Maity, Nirman Ganguly +1
Higher-dimensional entanglement is a valuable resource for several quantum information processing tasks, and is often characterized by the Schmidt number and specific classes of en…
