Generating Optical Schrödinger Kittens for Quantum Information Processing

Résumé

We present a detailed experimental analysis of a free-propagating light pulse prepared in a "Schrödinger kitten" state, defined as a quantum superposition of "classical" coherent states with small amplitudes. This state is generated by subtracting one photon from a squeezed vacuum beam, and it clearly presents a negative Wigner function. The predicted influence of the experimental parameters is in excellent agreement with the experimental results. The amplitude of the coherent states can be amplified to transform our "Schrödinger kittens" into bigger Schrödinger cats, providing an essential tool for quantum information processing.
