    "abstract": "We describe a fast quantum computer based on optically controlled electron\nspins in charged quantum dots that are coupled to microcavities. This scheme\nuses broad-band optical pulses to rotate electron spins and provide the clock\nsignal to the system. Non-local two-qubit gates are performed by phase shifts\ninduced by electron spins on laser pulses propagating along a shared waveguide.\nNumerical simulations of this scheme demonstrate high-fidelity single-qubit and\ntwo-qubit gates with operation times comparable to the inverse Zeeman\nfrequency.",
