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.

Deny wins Dean of Science Award

Deny Hamel has been awarded the 2011 University of Waterloo Dean of Science Award for his MSc thesis, Realization of novel entangled photon sources using periodically-poled materials. Congratulations Deny!

The Dean of Science Award is given in recognition of outstanding performance in the Master of Science program. One certificate will normally be awarded annually to […]

Experimental Bound Entanglement in PRL

Experimental Bound Entanglement in a Four-Photon State by Jonathan Lavoie, Rainer Kaltenbaek, Marco Piani, and Kevin Resch was published today in Physical Review Letters.

Bound entanglement is central to many exciting theoretical results in quantum information processing, but has thus far not been experimentally realized. In this work, we consider a […]

Photonic hat-trick published in Nature

Direct generation of photon triplets using cascaded photon-pair sources by Hannes Hübel, Deny Hamel, Sven Ramelow, Alessandro Fedrizzi, Kevin Resch, and Thomas Jennewein was published today in Nature.

Parametric down-conversion is the most common source of entangled photon pairs. It uses a nonlinear optical process to split a pump photon, typically […]
