Quantum coherence: myth or fact?
Kae Nemoto, Samuel L. Braunstein
It has recently been argued that the inability to measure the absolute phase of an electromagnetic field prohibits the representation of a laser's output as a quantum optical coher…
Quantum Metrology: Detection of weak forces using Schrodinger Cat resources
Kae Nemoto, W. J. Munro, G. J. Milburn +1
We investigate the utility of non classical states of simple harmonic oscillators (a superposition of coherent states) for sensitive force detection. We find that like squeezed sta…
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.…
Quantum coherence in the presence of unobservable quantities
Kae Nemoto, Samuel L. Braunstein
State representations summarize our knowledge about a system. When unobservable quantities are introduced the state representation is typically no longer unique. However, this non-…
Generating optical nonlinearity using trapped atoms
Alexei Gilchrist, G. J. Milburn, W. J. Munro +1
We describe a scheme for producing an optical nonlinearity using an interaction with one or more ancilla two-level atomic systems. The nonlinearity, which can be implemented using…
Measurement-induced Nonlinearity in Linear Optics
Stefan Scheel, Kae Nemoto, William J. Munro +1
We investigate the generation of nonlinear operators with single photon sources, linear optical elements and appropriate measurements of auxiliary modes. We provide a framework for…
