Description

Abstract:

The immense power of quantum computation is illustrated by flagship quantum algorithms that solve problems, such as factoring, much more efficiently than classical algorithms. The building of a quantum device with error rates well below the fault-tolerance threshold poses a challenge to the implementation of these quantum algorithms on near-term devices. In this talk, I will present the physics of superconducting circuits, one of the most promising technology for building Noisy Intermediate-Scale Quantum (NISQ) computers. In particular, I will explain the dispersive readout of a superconduting qubit and how to perform single qubit rotations and two-qubit parametric entangling gates. Finally, I will present an unsupervised machine learning algorithm that we have recently run on our quantum processing unit.

Bio Sketch:

Dr. Riccardo Manenti is a quantum engineer at Rigetti Computing, a quantum computing company based in Berkeley (CA). His work mainly focuses on the design and measurement of superconducting devices. Dr. Manenti earned his PhD at the University of Oxford (2017). His PhD thesis investigated the coupling between a superconducting qubit and a mechanical oscillator based on surface acoustic waves. His research contributed to the formation of a new field in hybrid quantum systems, now called circuit quantum acoustodynamics.
