Compressed optimization of device architectures
Adam Frees, John King Gamble, Daniel R. Ward +4
Note: This preprint has been superseded by arXiv:1806.04318. Recent advances in nanotechnology have enabled researchers to control individual quantum mechanical objects with unprec…
Multivalley effective mass theory simulation of donors in silicon
John King Gamble, N. Tobias Jacobson, Erik Nielsen +4
Last year, Salfi et al. made the first direct measurements of a donor wave function and found extremely good theoretical agreement with atomistic tight-binding [Salfi et al., Nat.…
Microwave-driven coherent operations of a semiconductor quantum dot charge qubit
Dohun Kim, D. R. Ward, C. B. Simmons +8
A most intuitive realization of a qubit is a single electron charge sitting at two well-defined positions, such as the left and right sides of a double quantum dot. This qubit is n…
Two-axis control of a singlet-triplet qubit with an integrated micromagnet
Xian Wu, D. R. Ward, J. R. Prance +9
The qubit is the fundamental building block of a quantum computer. We fabricate a qubit in a silicon double quantum dot with an integrated micromagnet in which the qubit basis stat…
Quantum control and process tomography of a semiconductor quantum dot hybrid qubit
Dohun Kim, Zhan Shi, C. B. Simmons +9
The similarities between gated quantum dots and the transistors in modern microelectronics - in fabrication methods, physical structure, and voltage scales for manipulation - have…
