Utilizing Encoding in Scalable Linear Optics Quantum Computing
A. J. F. Hayes, A. Gilchrist, C. R. Myers +1
We present a scheme which offers a significant reduction in the resources required to implement linear optics quantum computing. The scheme is a variation of the proposal of Knill,…
Distance measures to compare real and ideal quantum processes
Alexei Gilchrist, Nathan K. Langford, Michael A. Nielsen
With growing success in experimental implementations it is critical to identify a "gold standard" for quantum information processing, a single measure of distance that can be used…
Quantum process tomography of a controlled-NOT gate
J. L. O'Brien, G. J. Pryde, A. Gilchrist +4
We demonstrate complete characterization of a two-qubit entangling process - a linear optics controlled-NOT gate operating with coincident detection - by quantum process tomography…
