Quantum Computing with Semiconductor Nanophotonics
Thaddeus D. LaddE. L. Ginzton Lab, Stanford University and the National Institute of Informatics, Tokyo
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.
