Introduction

We are an experimental quantum optics group run by Kevin Resch, based in the Department of Physics & Astronomy and the Institute for Quantum Computing at the University of Waterloo.

Automatic dispersion cancellation is one of the hallmark features of quantum interference, but does it really need any quantum resources?  In this paper we demonstrate a new interference technique, called chirped-pulse interferometry, which exhibits automatic dispersion cancellation without entanglement or any quantum effects.  No longer constrained to running two photons at a time, the signal is orders of magnitude larger than what can be obtained with entanglement.  The technique relies on oppositely chirped laser pulses which have classical, as opposed to quantum, frequency correlations.
