Contextuality and Wigner negativity are equivalent for continuous-variable quantum measurements
Robert I. Booth, Ulysse Chabaud, Pierre-Emmanuel Emeriau
Quantum computers will provide considerable speedups with respect to their classical counterparts. However, the identification of the innately quantum features that enable these sp…
Holomorphic representation of quantum computations
Ulysse Chabaud, Saeed Mehraban
We study bosonic quantum computations using the Segal-Bargmann representation of quantum states. We argue that this holomorphic representation is a natural one which not only gives…
Continuous Variable Quantum Advantages and Applications in Quantum Optics
Ulysse Chabaud
This thesis focuses on three main questions in the continuous variable and optical settings: where does a quantum advantage, that is, the ability of quantum machines to outperform…
Witnessing Wigner Negativity
Ulysse Chabaud, Pierre-Emmanuel Emeriau, Frédéric Grosshans
Negativity of the Wigner function is arguably one of the most striking non-classical features of quantum states. Beyond its fundamental relevance, it is also a necessary resource f…
Quantum machine learning with adaptive linear optics
Ulysse Chabaud, Damian Markham, Adel Sohbi
We study supervised learning algorithms in which a quantum device is used to perform a computational subroutine - either for prediction via probability estimation, or to compute a…
