Modified non-linear Schrödinger models, symmetry, dark solitons and infinite towers of anomalous charges
H. Blas, M. Cerna Maguiña, L. F. dos Santos
Some modified (defocusing) non-linear Schrödinger models (MNLS) possess infinite towers of anomalous conservation laws with asymptotically conserved charges. The so-called anomalie…
An Analytical Solution for the Wigner-Boltzmann Transport Equation in the Relaxation Time Approximation
A. R. Fernandes Nt., L. F. Santos
The quantum version of the Boltzmann transport equation (Wigner-Boltzmann equation) is a quite useful tool to investigate the effects of energy dissipation in quantum systems. Nume…
Fault-Tolerant Landau-Zener Quantum Gates
C. Hicke, L. F. Santos, M. I. Dykman
We present a method to perform fault-tolerant single-qubit gate operations using Landau-Zener tunneling. In a single Landau-Zener pulse, the qubit transition frequency is varied in…
Many-particle confinement by constructed disorder and quantum computing
M. I. Dykman, L. F. Santos, M. Shapiro
Many-particle confinement (localization) is studied for a 1D system of spinless fermions with nearest-neighbor hopping and interaction, or equivalently, for an anisotropic Heisenbe…
Creation of Stable Multipartite Entangled States in Spin Chains with Defects
L. F. Santos
We show how defects in a spin chain described by the XXZ model may be used to generate entangled states, such as Bell and W states, and how to maintain them with high fidelity. In…
Many-particle localization by constructed disorder: enabling quantum computing with perpetually coupled qubits
M. I. Dykman, F. M. Izrailev, L. F. Santos +1
We demonstrate that, in a many-particle system, particles can be strongly confined to their sites. The localization is obtained by constructing a sequence of on-site energies that…
