Building a quantum computer using silicon quantum dots

Presenting Author: Susan Coppersmith, (Wisconsin-Madison)

This talk will discuss work at University of Wisconsin-Madison that aims to build a quantum computer using electrically-gated quantum dots in silicon. We have proposed and implemented a new "hybrid quantum dot qubit," which has an attractive combination of speed and fabrication simplicity [1]. Recent experimental and theoretical results demonstrating substantial progress towards high fidelity operation will be presented [2,3]. [1] Z. Shi, et al., Phys. Rev. Lett. 108, 140503 (2012). [2] D.
