### VICTOR VEITCH THESIS

Cite this version of the work Victor Veitch Negative Quasi-probability in the Context of Quantum Computation. This thesis is concerned with advancing the confrontation between relativistic quantum information RQI and experiment. The key technical challenge in this setting is that standard statistical assumptions do not hold. In particular, we study what resources are required to promote fault tolerant stabilizer computation to universal quantum computation. Read, highlight, and take notes, across web, tablet, and phone.

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. Pierre Robillard Award Call for Nominations.

He earned a BSc in mathematical physics from the University of Waterloo, and later earned a MMath, also from Waterloo, working in 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.

In particular, we study what resources are required to promote fault tolerant stabilizer computation to universal quantum computation. The key technical challenge in this setting is that standard statistical assumptions do not hold. Victoor 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.

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. 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.

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.

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.

Transmitting quantum information across vwitch channels is an important task. Victor’s thesis makes an in-depth study of this new model, uncovering sampling interpretations and identifying canonical estimators.
