We investigate the lessons that some present-day experiments can teach us about the relationship This gives a precise, quantitative meaning to the negativity of a quasi-probability representation, thereby resolving the 80 year debate as to whether this quantity is a meaningful indicator of quantum behaviour. Pierre Robillard Award Call for Nominations. This new model contains the popular stochastic block model indeed, every exchangeable graph model as a submodel, but also permits sparsely connected graphs, which are believed to better capture the statistics of real-world networks. Victor’s thesis makes an in-depth study of this new model, uncovering sampling interpretations and identifying canonical estimators. Victor is from Waterloo, Ontario. This connection allows us to establish a number of important results related to magic state computation, an important model for fault tolerant quantum computation using stabilizer operations supplemented by the ability to prepare noisy non-stabilizer ancilla states.

In particular, we study what resources are required to promote fault tolerant stabilizer computation to universal quantum computation. His work also makes substantial contributions to the theory of graph limits.

# [] Negative Quasi-Probability as a Resource for Quantum Computation

Moreover, by casting magic state computation as resource theory we are able to quantify how useful ancilla resource states are for quantum computation, which allows us to give bounds on the required resources.

We investigate the lessons that some present-day experiments can teach us about the relationship In this context we discover that the sum of the negative entries of the discrete Wigner representation of a state is a measure of its usefulness for quantum computation.

Recent advances in quantum technologies enabled us to make large quantum states and pushed towards examining quantum theory at the macroscopic level. Skip to main content.

## Victor Veitch, Pierre Robillard Award 2018

This thesis deals with the question of what resources are necessary and sufficient for quantum computational speedup. Victor’s research on sparse graph models, graph limits, and estimation has made foundational contributions to network data analysis and more generally, the problem of modeling relational data.
