Homodyne detection of temporally resolved quantum states
Abstract
Abstract We present an analysis of the time domain measurement of temporally resolvable quantum states using balanced homodyne detection. Our approach outlines a formalism of detecting quantum states in arbitrary temporal modes via projection of the temporal mode onto a natural detector basis. We then present an algorithm for simulating the resultant photocurrent of continuous homodyne detection in the presence of a temporally resolved mode, and use this algorithm to explore the effects of realistic measurement errors on reconstruction of the marginal probability distribution and quantum state tomography. A complete implementation of the method is provided through open source code on a GitHub repository.
