Dynamical protection of quantum steering and fidelity dynamics in the double Jaynes-Cummings model
Koushik Mandal, Chitra Rangan, Shohini Ghose
We investigate the dynamics of Einstein-Podolsky-Rosen (EPR) steering in a double Jaynes-Cummings model, where two initially entangled spatially separated two-level atoms in two ca…
Superposed quantum evolutions across chaotic and regular regimes
Amit Anand, Anne-Catherine de la Hamette, Robert Mann +1
While the superposition of quantum evolutions is known to produce interference effects, the interference between evolutions with regular and chaotic classical limits remains largel…
Quantum recurrences and the arithmetic of Floquet dynamics
Amit Anand, Dinesh Valluri, Jack Davis +1
The Poincaré recurrence theorem shows that conservative systems in a bounded region of phase space eventually return arbitrarily close to their initial state after a finite amount…
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,…
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…
Quantum recurrences in the kicked top
Amit Anand, Jack Davis, Shohini Ghose
The correspondence principle plays an important role in understanding the emergence of classical chaos from an underlying quantum mechanics. Here we present an infinite family of q…
