Department of Physics
Condensed Matter Seminar

Recently there has been much focus on utilizing vastly different experimental systems to create few qubit systems. In the introduction to this talk I will briefly review the application of one such system, lateral few electron quantum dots, as spin qubits which has served as motivation for our recent effort to develop more complex quantum dot circuits. Most of the work to date has been performed on single or coupled quantum dots. In the main part of the talk I will describe our recent investigations of triple quantum dots from measurements of the underlying stability diagram to coherent transport. The talk will also emphasize some of the experimental challenges and techniques that need to be controlled and mastered in this field from overcoming switching noise to time resolved charge detection of single electron events.
