Thermodynamics has been highly successful, impacting strongly on the natural sciences and enabling the development of technologies that have changed our lives, from fridges to jet planes. Until recently, it was applied to large systems described by the laws of classical physics. However, with modern technologies miniaturizing down to the nanoscale and into the quantum regime, testing the applicability of thermodynamics in this new realm has become an exciting technological challenge.

Nonequilibrium quasiparticles and trapped magnetic flux vortices can significantly impact the performance of superconducting microwave resonant circuits and qubits at millikelvin temperatures. Quasiparticles result in excess loss, reducing resonator quality factors and qubit lifetimes. Vortices trapped near regions of large microwave currents also contribute excess loss. However, vortices located in current-free areascan actually trap quasiparticles and lead to a reduction in the quasiparticle loss.

We introduce an approach to homomorphic encryption on quantum data.
Homomorphic encryption is a cryptographic scheme that allows
evaluations to be performed on ciphertext without giving the evaluator
access to the secret encryption key. Random operations from an finite
abelian unitary group chosen using an encryption key chosen
uniformly at random perform the encryption, and operations that lie
within the centralizer of the encryption group perform the

Quantum-optical frequency conversion (QFC) provides a method, usually via a nonlinear interaction with an optical ‘pump’ beam, to keep the quantum features of an optical ‘signal’ intact. Most QFC experiments
upconvert near-infrared signal photons to those in the visible or near-visible regime due to the availability of highly-efficient detectors that can be operated at high speeds without incurring a severe noise penalty.

The Institute for Quantum Computing (IQC) will open its doors to all members of the community as part of Reunion at the University of Waterloo. Bring the whole family to discover the excitement of quantum mechanics and learn about the world-class research that is happening right here in our community!

Take a look at what's happening at this year's open house!

Celebrating light and light-based technologies

Join us at the Institute for Quantum Computing for a two-week introduction to the theoretical and experimental study of quantum information processing.

Public lecture by Bill Unruh, The University of British Columbia

On February 11, 2016 it was announced that gravitational  waves have been detected affecting an instrument on earth. In addition to the realization of a 100 year old prediction the astounding sensitivity of the detector demanded the approaching and overcoming of seemingly fundamental quantum limits on measuring the motion of 25Kg masses. Quantum mechanics is usually thought of applying only to the very small (zeptogrammes and nanometers).

Public lecture by Charles W. Clark

Much of what we understand about the world comes from our eyes, which sense the colors from red to violet that are expressed in the rainbow.

Short film festival + public lecture by Martin Laforest

Join us for a night of film and science. The Institute for Quantum Computing has partnered with the Centre for Quantum Technologies in Singapore to host a festival for quantum-inspired films. The screening of the top 10 short films will be followed by a lecture by Senior Manager, Scientific Outreach, Martin Laforest about the applications of quantum devices. He will delve into what we know quantum devices will be used for (that will affect everyone) and where researchers are hoping they will be used in the future.
