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.

Producing Polarization Entangled States Using a Bright Single Photon Source

Neil Julien Ross, Dalhousie University

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

The toric code is a topological quantum error correcting code, and an example of a stabilizer code, defined on a two-dimensional spin lattice. It also represents the simplest example of topological order -- Z2 topological order that was first studied in the context of Z2 spin liquid. I will talk about our recent progress in the search for a toric code topological order in the kagome antiferromagnetic spin system.
