Unbounded Sharing of Nonlocality Using Projective Measurements
S. Sasmal, S. Kanjilal, A. K. Pan
It is a common perception that a sharp projective measurement in one side of the Bell experiment destroys the entanglement of the shared state, thereby preventing the demonstration…
Self-testing of an unbounded number of mutually commuting local observables
Sneha Munshi, A. K. Pan
Based on the optimal quantum violation of suitable Bell's inequality, the device-independent self-testing of state and observables has been reported. It is well-studied that locall…
Optimal quantum violations of n-locality inequalities with conditional dependence on inputs
Sneha Munshi, A. K. Pan
Bell experiment in the network gives rise to a form of quantum nonlocality which is conceptually different from traditional multipartite Bell nonlocality. Conventional multipartite…
Device-independent certification of degeneracy-breaking measurements
Prabuddha Roy, Shyam Sundar Mahato, Sumit Mukherjee +1
In a device-independent Bell test, the devices are considered to be black boxes and the dimension of the system remains unspecified. The dichotomic observables involved in such a B…
Sharing nonlocality in a network using the quantum violation of chain network inequality
Rahul Kumar, A. K. Pan
Based on the quantum violation of suitable -local inequality in a star network for arbitrary inputs, we demonstrate the sharing of nonlocality in the network. Such a network…
Generalized parity-oblivious communication games powered by quantum preparation contextuality
Prabuddha Roy, A. K. Pan
The parity-oblivious random-access-code (PORAC) is a class of communication games involving a sender (Alice) and a receiver (Bob). In such games, Alice's amount of communication to…
Device-independent self-testing of unsharp measurements
Prabuddha Roy, A. K. Pan
Semi-device-independent certification of an unsharp instrument has recently been demonstrated [New J. Phys. 21, 083034 (2019)] based on the sequential sharing of quantum advantages…
