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

Nitin Jain: Enabling high-speed quantum communication and foiling quantum hackers

Nitin Jain, Northwestern University

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.

Chris Granade: Practical Bayesian Tomography

Chris Granade, University of Sydney

In recent years, Bayesian methods have been proposed as a solution to a wide range of issues in quantum state and process tomography. In this talk, we make these methods practical by solving three distinct problems: numerical intractability, a lack of informative prior distributions, and an inability to track time-dependent processes. Our approach allows for practical computation of point and region estimators for quantum states and channels, and allows tracking of time-dependent states.

2015 Open House

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!

LIGHT Illuminated at THEMUSEUM

Celebrating light and light-based technologies

LIGHT Illuminated celebrates the United Nation's International Year of Light. In this interactive exhibition at THEMUSEUM you can learn about the value and importance of light-based technologies by exploring a black-light room, playing with colour mixing stations, and trying to get through a laser maze.

The behavior of conventional transistors derives from large numbers of acceptor and donor impurities that promote carriers into the valence and conduction bands. More recently, nano-electronic devices based on the bound states of individual dopant impurities in silicon have received considerable attention for quantum computation, due to the long spin coherence times of dopants in silicon. This invariably requires control over dopant wavefunctions and the interactions between individual dopants [1].
