Parameters of Pseudo-Random Quantum Circuits
Yaakov S. Weinstein, Winton G. Brown, Lorenza Viola
Pseudorandom circuits generate quantum states and unitary operators which are approximately distributed according to the unitarily invariant Haar measure. We explore how several de…
Quantum pseudo-randomness from cluster-state quantum computation
Winton G. Brown, Yaakov S. Weinstein, Lorenza Viola
We show how to efficiently generate pseudo-random states suitable for quantum information processing via cluster-state quantum computation. By reformulating pseudo-random algorithm…
Quantum Chaos, Delocalization, and Entanglement in Disordered Heisenberg Models
Winton G. Brown, Lea F. Santos, David J. Starling +1
We investigate disordered one- and two-dimensional Heisenberg spin lattices across a transition from integrability to quantum chaos from both a statistical many-body and a quantum-…
Generalized entanglement as a framework for complex quantum systems: Purity vs delocalization measures
Lorenza Viola, Winton G. Brown
We establish contact between the delocalization properties of pure quantum states, as quantified by their number of principal components, and the average generalized entanglement p…
