Abstract
In this paper we present a quantum logic circuit which can be used for the experimentaldemonstration of a three-qubit solid state quantum computer based on a recent proposal ofoptically driven quantum logic gates. In these gates, the entanglement of randomly placedelectron spin qubits is manipulated by optical excitation of control electrons. The circuit wedescribe solves the Deutsch problem with an improved algorithm called the refinedDeutsch–Jozsa algorithm. We show that it is possible to select optical pulses that solve theDeutsch problem correctly, and do so without losing quantum information to the controlelectrons, even though the gate parameters vary substantially from one gate to another.
