Nonlinear Models in Quantum Optics through Quantum Algebras

with a, b, c being boson operators for three different modes of the radiation field, describes (under certain conditions) nonlinear quantum optical processes as frequency conversion and Raman and Brillouin scattering [1]. Through a Jordan–Schwinger transformation, this model is algebraically equivalent to the resonant interaction of a sample of two-level atoms with a single mode of the quantize...

Error models for mode-mismatch in linear optics quantum computing

One of the most significant challenges facing the development of linear optics quantum computing (LOQC) is mode-mismatch, whereby photon distinguishability is introduced within circuits, undermining quantum interference effects. We examine the effects of mode-mismatch on the parity (or fusion) gate, the fundamental building block in several recent LOQC schemes. We derive simple error models for...

Recent Developments in Quantum Optics

he quantum theory of light predicts many interesting effects that may seem counterintuitive or even impossible from a classical point of view. Several effects of this kind have been investigated at the Applied Physics Laboratory, including a new kind of interferometry, the cancellation of dispersion between two distant media, and a new type of phase associated with the electromagnetic field. So...
