I will report on dynamical magnetic susceptibility measurements of
both bulk and thin film samples of the spin glass Copper Manganese.
By studying the Thermoremanent Magnetization (TRM) of multi-layer thin
films of various thicknesses, we are able to show the maximum energy
barrier encountered during correlated spin flip transitions is cut off
by the thickness of the film and is independent of temperature. The
distribution of energy barriers is shown to follow from a hierarchical

Motivated by their necessity for most fault-tolerant quantum computation schemes, we formulate a resource theory for magic states. We first show that robustness of magic is a well-behaved magic monotone that operationally quantifies the classical simulation overhead for a Gottesman-Knill type scheme using ancillary magic states. Our framework subsequently finds immediate application in the task of synthesizing non-Clifford gates using magic states.

Assessing the Practicality of a Simple Multi-node Quantum Repeater
Christopher is supervised by IQC faculty member Norbert Lütkenhaus.
The Quantum Innovators in science and engineering workshop brings together the most promising young researchers in quantum physics and engineering. Guests are invited for a four-day conference aimed at exploring the frontier of our field.
The modern conception of phases of matter has undergone tremendous developments since the first observation of topologically ordered states in fractional quantum Hall systems in the 1980s. In this paper, we explore the question: How much detail of the physics of topological orders can in principle be observed using state of the art technologies?
Hear Raymond Laflamme, founding director of the Institute for Quantum Computing and John von Neumann Chair in Quantum Information and Edwin Outwater, Music Director Laureate of the Kitchener-Waterloo Symphony, as they have a conversation about the making of Does God Play Dice (Quantum Etude).
Radio host Mike Farwell will moderate this conversation about their collaboration that integrated quantum physics and music to create a surprisingly random performance piece. You’ll even have the to watch highlights of the April 20 performance.
As we approach the development of a quantum computer with tens of
well-controlled qubits, it is natural to ask what can be done with
such a device. Specifically, we would like to construct an example of
a practical problem that is beyond the reach of classical computers,
but that requires the fewest possible resources to solve on a quantum
computer. We address this problem by considering quantum simulation of
spin systems, a task that could be applied to understand phenomena in
