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…

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…
