Recent progress in the ultrafast optical control of single, semiconductor-based quantum dots shows strong promise for quantum computation. I will describe this progress and outline trade-offs in different technological choices for quantum dots. I will then indicate how multi-qubit logic may be performed, and introduce a sketch of a large-scale, fault-tolerant and defect-tolerant quantum computer architecture, employing quantum dots in optical microcavities connected by on-chip waveguides and drop-filter switches. I will highlight the key advantages of this hardware: high speed operation, and capabilities for efficient quantum communication.
