Self-testing quantum systems of arbitrary local dimension with minimal number of measurements
Shubhayan Sarkar, Debashis Saha, Jędrzej Kaniewski +1
Bell nonlocality as a resource for device independent certification schemes has been studied extensively in recent years. The strongest form of device independent certification is…
Can Quantum discord increase in a quantum communication task?
Shubhayan Sarkar, Chandan Datta
Quantum teleportation of an unknown quantum state is one of the few communication tasks which has no classical counterpart. Usually the aim of teleportation is to send an unknown q…
Entanglement renders free riding redundant in the thermodynamic limit
Shubhayan Sarkar, Colin Benjamin
The free rider problem is one of the most well-studied problems in economics. The solution proposed mainly is punitive in order to deter people from free riding. In this work, we i…
Entropy as a bound for expectation values and variances of a general quantum mechanical observable
Shubhayan Sarkar
Quantum information-theoretic approach has been identified as a way to understand the foundations of quantum mechanics as early as 1950 due to Shannon. However there hasn't been en…
Quantum Nash equilibrium in the thermodynamic limit
Shubhayan Sarkar, Colin Benjamin
The quantum Nash equilibrium in the thermodynamic limit is studied for games like quantum Prisoner's dilemma and the quantum game of chicken. A phase transition is seen in both gam…
Triggers for cooperative behavior in the thermodynamic limit: a case study in Public goods game
Colin Benjamin, Shubhayan Sarkar
In this work, we aim to answer the question: what triggers cooperative behavior in the thermodynamic limit by taking recourse to the Public goods game. Using the idea of mapping th…
