We analyse the design and optimisation of quantum logic circuits suitable forthe experimental demonstration of a three-qubit quantum computation prototypebased on optically-controlled, solid-state quantum logic gates. In these gates,the interaction between two qubits carried by the electron-spin of donors ismediated by the optical excitation of a control particle placed in theirproximity. First, we use a geometrical approach for analysing the entanglingcharacteristics of these quantum gates. Then, using a genetic programmingalgorithm, we develop circuits for the refined Deutsch-Jozsa algorithminvestigating different strategies for obtaining short total computationaltimes. We test two separate approaches based on using different sets ofentangling gates with the shortest possible gate computation time which,however, does not introduce leakage of quantum information to the controlparticles. The first set exploits fast approximations of controlled-phase gatesas entangling gates, while the other one arbitrary entangling gates with ashorter gate computation time compared to the first set. We have identifiedcircuits with consistently shorter total computation times when usingcontrolled-phase gates.
