A symmetry analyser for non-destructive Bell state detection using EIT
S. D. Barrett, P. Kok, K. Nemoto +3
We describe a method to project photonic two-qubit states onto the symmetric and antisymmetric subspaces of their Hilbert space. This device utilizes an ancillary coherent state, t…

A high-efficiency quantum non-demolition single photon number resolving detector
W. J. Munro, Kae Nemoto, R. G. Beausoleil +1
We discuss a novel approach to the problem of creating a photon number resolving detector using the giant Kerr nonlinearities available in electromagnetically induced transparency.…
