Superunsteerability as a quantifiable resource for random access codes assisted by Bell-diagonal states
C. Jebarathinam, Debarshi Das, Som Kanjilal +4
We show how nonclassical correlations in local bipartite states can act as a resource for quantum information processing. Considering the task of quantum random access codes (RAC)…
Facets of bipartite nonlocality sharing by multiple observers via sequential measurements
Debarshi Das, Arkaprabha Ghosal, Souradeep Sasmal +2
Recently, it has been shown that at most two observers (Bobs) can sequentially demonstrate bipartite nonlocality with a spatially separated single observer (Alice) invoking a scena…
Protecting temporal correlations of two-qubit states using quantum channels with memory
Shounak Datta, Shiladitya Mal, A. S. Majumdar
Quantum temporal correlations exhibited by violations of Leggett-Garg Inequality (LGI) and Temporal Steering Inequality (TSI) are in general found to be non-increasing under decohe…
Preservation of quantum non-bilocal correlations in noisy entanglement-swapping experiments using weak measurements
Shashank Gupta, Shounak Datta, A. S. Majumdar
A tripartite quantum network is said to be bilocal if two independent sources produce a pair of bipartite entangled states. Quantum non-bilocal correlation emerges when the central…
Environmental effects on nonlocal correlations
Tamal Guha, Bihalan Bhattacharya, Debarshi Das +6
Environmental interactions are ubiquitous in practical instances of any quantum information processing protocol. The interaction results in depletion of various quantum resources a…
Convex resource theory of non-Markovianity
Samyadeb Bhattacharya, Bihalan Bhattacharya, A. S. Majumdar
We establish a convex resource theory of non-Markovianity under the constraint of small time intervals within the temporal evolution. We construct the free operations, free states…
