Generalized -locality inequalities in a star-network configuration and their optimal quantum violations

S Munshi, R Kumar, AK Pan - Physical Review A, 2021 - APS
Network Bell experiments reveal a form of nonlocality conceptually different from standard
Bell nonlocality. Standard multiparty Bell experiments involve a single source shared by a …

Characterizing nonlocal correlations through various -locality inequalities in a quantum network

S Munshi, AK Pan - Physical Review A, 2022 - APS
The multipartite quantum networks feature multiple independent sources, in contrast to the
conventional multipartite Bell experiment involving a single source. Despite the initial …

Circulating genuine multiparty entanglement in a quantum network

P Halder, R Banerjee, S Ghosh, AK Pal, A Sen - Physical Review A, 2022 - APS
We propose a deterministic scheme of generating genuine multiparty entangled states in
quantum networks of arbitrary size having various geometric structures—we refer to it as …

Limits of network nonlocality probed by timelike-separated observers

P Halder, R Banerjee, S Mal, A Sen - Physical Review A, 2022 - APS
In an entanglement swap** scenario, if two sources distributing entangled states between
three parties are independent, local correlations lead to a different kind of inequality than the …

Measurement-based multipartite entanglement inflation

P Halder, S Mal, A Sen - Physical Review A, 2021 - APS
Generating entanglement between more parties is one of the central tasks and challenges in
the backdrop of building quantum technologies. Here we propose a measurement-based …

Optimal Quantum Violations of n‐Locality Inequalities with Conditional Dependence on Inputs

S Munshi, AK Pan - Annalen der Physik, 2023 - Wiley Online Library
Bell experiment in a network gives rise to a form of quantum nonlocality which is
conceptually different from traditional multipartite Bell nonlocality. In this work, the star …

Detecting nonlocal correlations in chain-shaped quantum networks via a deep-learning method

Y Zhang, J Hou, K He - Physical Review A, 2024 - APS
As the demand for quantum networks and communication grows, identifying quantum
nonlocality in these networks has become a crucial and challenging task. The nonconvex …

Generalized n‐Locality Inequalities in Linear‐Chain Network for Arbitrary Inputs Scenario and Their Quantum Violations

R Kumar, AK Pan - Annalen der Physik, 2022 - Wiley Online Library
Multipartite nonlocality in a network is conceptually different from standard multipartite Bell
nonlocality. In recent times, network nonlocality has been studied for various topologies. A …

Duality between imperfect resources and measurements for propagating entanglement in networks

S Mondal, P Halder, AS De - arxiv preprint arxiv:2308.10975, 2023 - arxiv.org
We propose a measurement-based entanglement propagation strategy for networks in
which all nodes except two are initially occupied by a suitably chosen single-qubit system …

G Mylavarapu, I Chakrabarty, K Mukherjee… - arxiv preprint arxiv …, 2023 - arxiv.org
The most simplest form of quantum network is an one dimensional quantum network with a
single player in each node. In remote entanglement distribution each of the players carry out …
