Schrödinger Picture Analysis of the Beam Splitter: an Application of the Janszky Representation

  • Stephen M. BarnettEmail author


The Janszky representation constructs quantum states of a field mode as a superposition of coherent states on a line in the complex plane. We show that this provides a natural Schrödinger picture description of the interference between a pair of modes at a beam splitter.
