Abstract
Quantum Computers on Liquid Helium
You might know that in most of today's quantum computers, tiny superconducting circuits or trapped ions serve as qubits. But is it possible to build a quantum computer in which single electrons do the job? What would you use as the logic states, and how would you realize the 2-qubit gates necessary for fully customisable quantum computation?
This Friday, we present a schematic quantum computer in which electrons trapped on the surface of liquid helium serve as qubits. We will present 1D simulations of the system to illustrate relevant quantum properties and demonstrate how to drive an entangling √iSWAP gate through simple voltage control and natural electronic interaction. Spoiler: No spin involved!
The talk is based on the work in this paper, as well as more recent work on time evolution.
About the qGAP meeting series
Welcome to qGAP, our seminar series on Quantum Physics and Quantum Technology.
The series of seminars/lectures are meant to cover broadly activities at UiO and elsewhere related to quantum physics and technologies, mainly from a theoretical perspective, though we also welcome experimental talks.
We aim at having regular seminars, discussions of recent articles, presentations by master and PhD students and more. We aim for this series to be a combination of research talks and journal clubs.
Educational topics are also most welcome.
Please feel free to suggest speakers, yourself included!
Get in touch with Gunnar Lange to suggest a speaker or if you would like to be included in the mailing list.
All are welcome!
