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…
Persistence of quantum violation of macrorealism for large spins even under coarsening of measurement times
Sumit Mukherjee, Anik Rudra, Debarshi Das +2
We investigate quantum violation of macrorealism for multilevel spin systems under the condition of coarsening of measurement times -- i.e., when measurement times have experimenta…
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…
Witnessing entanglement sequentially: Maximally entangled states are not special
Anindita Bera, Shiladitya Mal, Aditi Sen De +1
We investigate sharing of bipartite entanglement in a scenario where half of an entangled pair is possessed and projectively measured by one observer, called Alice, while the other…
Inhibition of spreading in quantum random walks due to quenched Poisson-distributed disorder
Sreetama Das, Shiladitya Mal, Aditi Sen De +1
We consider a quantum particle (walker) on a line who coherently chooses to jump to the left or right depending on the result of toss of a quantum coin. The lengths of the jumps ar…
Canonical Leggett-Garg Inequality: Nonclassicality of temporal quantum correlations under energy constraint
Titas Chanda, Tamoghna Das, Shiladitya Mal +2
Nonclassicality of temporal correlations pertaining to noncommutative sequential measurements is defined through the violation of macrorealistic inequalities, known as Leggett-Garg…
