Effects of the interplay between interaction and disorder in bipartite entanglement
L. F. Santos, G. Rigolin
We use a disordered anti-ferromagnetic spin-1/2 chain with anisotropic exchange coupling to model an array of interacting qubits. All qubits have the same level spacing, except two…
Strong many-particle localization and quantum computing with perpetually coupled qubits
L. F. Santos, M. I. Dykman, M. Shapiro +1
We demonstrate the onset of strong on-site localization in a one-dimensional many-particle system. The localization is obtained by constructing, in an explicit form, a bounded sequ…
Integrability of a disordered Heisenberg spin-1/2 chain
L. F. santos
We investigate how the transition from integrability to nonintegrability occurs by changing the parameters of the Hamiltonian of a Heisenberg spin-1/2 chain with defects. Randomly…
Entanglement versus chaos in disordered spin chains
L. F. Santos, G. Rigolin, C. O. Escobar
We use a Heisenberg spin-1/2 chain to investigate how chaos and localization may affect the entanglement of pairs of qubits. To measure how much entangled a pair is, we compute its…
Entanglement in quantum computers described by the XXZ model with defects
L. F. Santos
We investigate how to generate maximally entangled states in systems characterized by the Hamiltonian of the XXZ model with defects. Some proposed quantum computers are described b…
Quantum open systems and turbulence
L. F. Santos, C. O. Escobar
We show that the problem of non conservation of energy found in the spontaneous localization model developed by Ghirardi, Rimini and Weber is very similar to the inconsistency betw…
