Abstract

We present our implementation of an optical homodyne detector used to measure optical Schrödinger cat states. We show how we minimized the losses and mode-mismatches associated with homodyne detection, which become important when measuring non-classical states of light. We present a pulse shaping scheme applied to the local oscillator to improve its temporal mode overlap with the non-classical state.
