Description
TITLE: "Quantum Engineering in Silicon”
ABSTRACT: In the global race to build a quantum computer, there are many technologies competing to form the basic unit of quantum information – the quantum bit (or qubit). In recent years, individual electron spins trapped in silicon quantum dots have emerged as a leading technology. Silicon is an ideal host material for spin qubits as it supports long coherence times, has excellent prospects for scaling, and is ubiquitous in the semiconductor industry. While semiconductor spin qubits were proposed over two decades ago, it is only within the past few years that we have learned how to reliably fabricate and control multi-qubit devices in silicon. In this seminar, I will describe how quantum dot spin qubits work, highlighting recent advances in quantum control and readout. I will then discuss exciting opportunities for spin qubit architectures, including an overview of ongoing work in the Sigillito lab at the University of Pennsylvania.
