Quantum Computing over the Rainbow

Abstract:
Quantum light, already at the heart of quantum sensing and quantum communication, can also be key to implementing quantum simulation and quantum computing. In this talk, I'll present how my research group pioneered the use of the optical frequency comb in quantum optics to encode quantum information in continuous variables (CV), i.e. quantum fields rather than qubits, and generate record-scale cluster entangled states, an essential resource for measurement-based, universal quantum computing. I will also present how photon-number-resolving measurement of CV cluster states can yield fault-tolerant qubit cluster states, our current research effort.
