At Waterloo, a group of cutting-edge researchers are exploring the mysteries of the quantum universe.

With members from the faculties of science, mathematics, and engineering, the Institute for Quantum Computing (IQC) aims to transform computing and communications based on quantum mechanics — how nature behaves at the atomic level, where particles may exist in several states at once.

Thomas Jennewein, Adrian Lupacu, and Kevin Resch are just a few of the rising stars at IQC conducting research that is already making an impact.

Resch looks at the properties of light at its dimmest imaginable levels.

 

Our research, in collaboration with Thomas Jennewein, recently achieved a milestone in quantum optics with the generation of photon triplets,” Resch says. “This result has been sought after for years but never achieved before now.

Lupaşcu is investigating quantum information processing primarily through the use of superconducting materials.

By using non-traditional quantum systems, like artificial atoms, I’m hoping that we’ll be able to tailor quantum properties in these systems to enable novel applications,” says Lupaşcu.

And Jennewein is currently leading a collaboration that will explore the boundaries of quantum entanglement and quantum cryptography in space via satellites.

The satellite transmission I’ve emulated in my lab is performing far better than existing systems, showing the viability of the concepts," Jennewein says. “Using satellites for quantum transmissions could open up a lot of possibilities for quantum technologies.
