Topological Quantum Gates with Quantum Dots
arXiv:quant-ph/0302077 · doi:10.1088/1464-4266/5/6/016
Abstract
We present an idealized model involving interacting quantum dots that can support both the dynamical and geometrical forms of quantum computation. We show that by employing a structure similar to the one used in the Aharonov-Bohm effect we can construct a topological two-qubit phase-gate that is to a large degree independent of the exact values of the control parameters and therefore resilient to control errors. The main components of the setup are realizable with present technology.
