Multipartite entanglement vs nonlocality for two families of -qubit states
Sanchit Srivastava, Shohini Ghose
Entangled states of multiple qubits can violate Bell-type inequalities indicating nonlocal behavior of multiqubit quantum correlations. We analyze the relation between multipartite…

Contextuality and Chaos
Sanchit Srivastava, Shohini Ghose
Classical chaos is marked by an extreme sensitivity to initial conditions, where infinitesimally close trajectories separate exponentially over time. In quantum mechanics, however,…

Non-classical correlations between a quantum probe and complex quantum systems in presence of noise
Bijoy John Mathew, Sanchit Srivastava, Anil Shaji
Non-classical correlations generated within a quantum probe system when it interacts with a large, macroscopic system can signal the presence of quantum features in the latter. The…
