Quantum information science and technology and silicon quantum electronics at CSUSM

Dr. Justin Perron

Department of Physics, California State University, San Marcos

Quantum information science and technology is a field built on the idea of harnessing the unusual and often counterintuitive aspects of quantum mechanics for new technologies. In this talk I will motivate the increasing interest in the field and give an overview of my group’s experimental efforts in silicon quantum electronics (SiQE). SiQE devices use the same physics involved in field effect transistors to isolate individual electrons. I will present the basic operation of these devices as well as present our recent results which use a gate-defined quantum dot as a charge sensor for a single dopant atom. We demonstrate single-shot readout of donor ionization, and apply a statistical tool known as the Allan variance to the current measured in our charge sensor and correlate features in the variance to specific two-level fluctuator coupled to the dot.
