Abstract

Pure optical squeezing in a single mode is highly desirable for quantum information applications such as continuous variable quantum computing and the generation of optical Schrödinger cat states. To generate optical cat states, photons are subtracted from squeezed light. Both the created quantum state and the subtracted photons must overlap with all modes (spatial, spectral, temporal) of the measurement apparatus, i.e. the homodyne detector and the photon-subtraction-arm single-mode fiber. This implies that the squeezed state must be in a single mode, allowing for all the subtracted photons to match the mode of the local oscillator. Here, we describe the experimental realization and characterization of such a source at telecom wavelengths.
