Witness-based quantification of non-Markovianity without complete Choi state reconstruction
Pritam Roy, Saheli Mukherjee, Bivas Mallick
Quantifying non-Markovianity is a fundamental problem in the theory of open quantum systems, as it is essential for exploiting environmental memory as a resource in quantum technol…
Maximizing Nonclassicality of Massive Objects via Quantum Zeno Effect
Debarshi Das, Pritam Roy, Marko Toroš +3
For testing quantum mechanics in the macroscopic domain, a major challenge is to devise effective means for enhancing the observable nonclassical signatures despite the ubiquitous…
Limits on Broadcasting Genuine Multipartite Entanglement in Quantum Networks
Pritam Roy, William John Munro, Shashank Gupta
We establish operational limits on the broadcasting of genuine multipartite entanglement (GME) in quantum networks. Using a distributed protocol in which each of N parties locally…
Exclusion reshapes the operational manifestation of preparation contextuality
Pritam Roy, Thansingh Jankawat, Ranendu Adhikary +1
Replacing the task of retrieval with exclusion changes how preparation contextuality manifests operationally under parity-oblivious constraints, with exclusion showing a quantum ad…
