Inspired by quantum physics - short films and devices

Martin Laforest giving a public lecture February 23

“Weird.” Amusing.” “What’s with the cat?” These are all phrases that were heard at the Institute for Quantum Computing (IQC) on Thursday, February 23.

Novel waveguide designs for quantum information processing with photons

IQC researchers propose two possible methods for building an optical cavity inside a hollow-core on-chip waveguide, to develop a platform for quantum information processing through photon-photon interactions.

Pushing the upper bounds of a long-standing test

IQC PhD student Hemant Katiyar led the first experiment to violate the Leggett-Garg inequality on a three-level quantum system, demonstrating the possibility of larger violations than previously thought possible.

Researchers successfully demonstrate prototype for space-based quantum-secured communication

A secure uplink is created between Alice and Bob as the NRC's Twin Otter Airborne Research Aircraft flies overhead.

Waterloo, Ont. (Wednesday, December 21, 2016) — Researchers from the Institute for Quantum Computing at the University of Waterloo in Canada are the first to transmit a quantum key securely from a source on the ground to a receiver on an aircraft. The uplink is a prototype for secure quantum communication and shows the viability of the team’s quantum communication satellite mission (QEYSSat) proposal.

Photonic entanglement takes on a new shape

Experimental setup for photonic entanglement shaping

A team of researchers from the Institute for Quantum Computing (IQC) has developed a process for reshaping the entanglement of two photons, demonstrating a new set of tools useful for quantum-state engineering.

Visualizing randomness

Randomness: A visual study of the Big Bell Test

Local artist creates visual project from random BIG Bell Test data

Do atoms behave differently when we are not looking at them?

The Bell test seeks to catch quantum particles “talking” to each other by matching their answers (output), to the questions asked (measurement). Unpredictable and independent input is one condition needed to perform Bell test experiments. Last week, the BIG Bell Test (BBT) brought true human unpredictability and randomness to the first ever human-driven Bell test.
