CVMBQC with phase-space measurements
Exploratory theory project, interactions with Ulysse Chabaud, Harold Ollivier and collaborators
Measurement-based quantum computing (MBQC) is a paradigm for quantum computing, in which the computation is performed by successive measurements and local operations on a large initial entangled state. Photonic platforms are particularly suited for MBQC, as they allow for the deterministic generation of large entangled states. For qubit computations, MBQC employs Pauli measurements to drive the computation, while continuous-variable (CV) MBQC employs CV homodyne measurements. However, other types of measurements are available such as phase-space measurements, corresponding to displaced parity operators whose mathematical properties resemble those of Pauli operators.
The proposed project aims to explore the possibility of using phase-space measurements to drive a CV quantum computation. A first step will be to study CV state teleportation based on phase-space measurements and classical communication. Then, a second step will be to generalise the construction to universal MBQC. Finally, a third step will be to study fault-tolerance in this computational model.
