Entanglement measures in quantum and classical chaos
Arul Lakshminarayan, Jayendra N. Bandyopadhyay, M. S. Santhanam +1
Entanglement is a Hilbert-space based measure of nonseparability of states that leads to unique quantum possibilities such as teleportation. It has been at the center of intense ac…
Entangling power of quantum chaotic evolutions via operator entanglement
Jayendra N. Bandyopadhyay, Arul Lakshminarayan
We study operator entanglement of the quantum chaotic evolutions. This study shows that properties of the operator entanglement production are qualitatively similar to the properti…
Cyclic Identities Involving Ratios of Jacobi Theta Functions
Avinash Khare, Arul Lakshminarayan, Uday Sukhatme
Identities involving cyclic sums of terms composed from Jacobi elliptic functions evaluated at equally shifted points were recently found. The purpose of this paper is to re-ex…
Entanglement production in coupled chaotic systems : Case of the Kicked Tops
Jayendra N. Bandyopadhyay, Arul Lakshminarayan
Entanglement production in coupled chaotic systems is studied with the help of kicked tops. Deriving the correct classical map, we have used the reduced Husimi function, the Husimi…
What is random about a quantum random walk?
Arul Lakshminarayan
We use simple deterministic dynamical systems as coins in studying quantum walks. These dynamical systems can be chosen to display, in the classical limit, a range of behaviors fro…
The classical counterpart of entanglement
Arul Lakshminarayan
We define and explore the classical counterpart of entanglement in complete analogy with quantum mechanics. Using a basis independent measure of entropy in the classical Hilbert sp…
