Biography

Prof. Nicolas Quesada’s expertise lies at the intersection of quantum photonics, optics and information. His group develops the theory and computational tools underpinning the next generation of nonclassical bright light sources and devices needed for building fault-tolerant quantum computers, quantum communication networks and quantum sensors.

Prior to joining Polytechnique Montréal as an MEI research chair in Quantum Photonics, Prof. Quesada worked at Xanadu Quantum Technologies as a lead developer of Strawberry Fields and The Walrus software libraries and led the theoretical efforts to demonstrate photonic quantum advantage.

Before joining industry, he was an NSERC postdoctoral fellow and, as a Ph.D. student, a Vanier scholar and a Stoicheff scholar.
