Creating ensembles of dual unitary and maximally entangling quantum evolutions
Suhail Ahmad Rather, S. Aravinda, Arul Lakshminarayan
Maximally entangled bipartite unitary operators or gates find various applications from quantum information to being building blocks of minimal models of many-body quantum chaos, a…
Quantum chaos and macroscopic realism as no-signaling in time
Manish Ramchander, Arul Lakshminarayan
Macroscopic realism is a set of assumptions about how we experience the world at a classical level. While the Leggett-Garg inequalities are temporal correlations that are violated…
Out-of-time-order correlators in bipartite nonintegrable systems
Ravi Prakash, Arul Lakshminarayan
Out-of-time-order correlators (OTOC) being explored as a measure of quantum chaos, is studied here in a coupled bipartite system. Each of the subsystems can be chaotic or regular a…
Entanglement production by interaction quenches of quantum chaotic subsystems
Jethin J. Pulikkottil, Arul Lakshminarayan, Shashi C. L. Srivastava +2
The entanglement production in bipartite quantum systems is studied for initially unentangled product eigenstates of the subsystems, which are assumed to be quantum chaotic. Based…
Entanglement measures of bipartite quantum gates and their thermalization under arbitrary interaction strength
Bhargavi Jonnadula, Prabha Mandayam, Karol Życzkowski +1
Entanglement properties of bipartite unitary operators are studied via their local invariants, namely the entangling power and a complementary quantity, the gate typicality $…
Scrambling in strongly chaotic weakly coupled bipartite systems: Universality beyond the Ehrenfest time-scale
Ravi Prakash, Arul Lakshminarayan
Out-of-time-order correlators (OTOC), vigorously being explored as a measure of quantum chaos and information scrambling, is studied here in the natural and simplest multi-particle…
