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. The Canadian Journal of Statistics Award. In this context we discover a remarkable connection between the possibility of quantum computational speedup and negativity in the discrete Wigner function, which is a particular distinguished quasi-probability representation for quantum theory.

The Canadian Journal of Statistics Award. 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. 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. Victor’s thesis makes an in-depth study of this new model, uncovering sampling interpretations and identifying canonical estimators. Victor is from Waterloo, Ontario. In this context we discover a remarkable connection between the possibility of quantum computational speedup and negativity in the discrete Wigner function, which is a particular distinguished quasi-probability representation for quantum theory. He earned a BSc in mathematical physics from the University of Waterloo, and later earned a MMath, also from Waterloo, working in quantum computation.

This thesis is concerned with advancing the confrontation between relativistic quantum information RQI and experiment.

However quantum information is delicate, and is easily corrupted. Ross Thomas J.

This new model contains the popular stochastic block model indeed, every vejtch graph model as a submodel, but also permits sparsely connected graphs, which are believed to better capture the statistics of real-world networks. In particular, we study what resources are required to promote fault tolerant stabilizer computation to universal quantum computation. Moreover, by casting magic state computation as resource vcitor we are able to quantify how useful ancilla resource states are for quantum computation, which allows us to give bounds on the required resources.

However observation of quantum e ects at a macroscopic level still Cite this version of the work Victor Veitch 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.

Transmitting quantum information across quantum channels is an important task. Victor Veitch, Pierre Robillard Award In particular, we resolve in the negative the open problem of whether every non-stabilizer resource suffices to promote computation with stabilizer operations to universal quantum computation.
