The Fourier transform of the Hadamard transform: Multifractals, Sequences and Quantum Chaos
N. Meenakshisundaram, Arul Lakshminarayan
We introduce a class of functions that limit to multifractal measures and which arise when one takes the Fourier transform of the Hadamard transform. This introduces generalization…
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…
Shuffling cards, factoring numbers, and the quantum baker's map
Arul Lakshminarayan
It is pointed out that an exactly solvable permutation operator, viewed as the quantization of cyclic shifts, is useful in constructing a basis in which to study the quantum baker'…
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…
Entanglement production in Quantized Chaotic Systems
Jayendra N. Bandyopadhyay, Arul Lakshminarayan
Quantum chaos is a subject whose major goal is to identify and to investigate different quantum signatures of classical chaos. Here we study entanglement production in coupled chao…
