Effects of charge noise on a pulse-gated singlet-triplet qubit
Zhenyi Qi, X. Wu, D. R. Ward +11
We study the dynamics of a pulse-gated semiconductor double quantum dot qubit. In our experiments, the qubit coherence times are relatively long, but the visibility of the quantum…
Characterization of a gate-defined double quantum dot in a Si/SiGe nanomembrane
T. J. Knapp, R. T. Mohr, Yize Stephanie Li +9
We report the fabrication and characterization of a gate-defined double quantum dot formed in a Si/SiGe nanomembrane. In the past, all gate-defined quantum dots in Si/SiGe heterost…
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…
Fast coherent manipulation of three-electron states in a double quantum dot
Zhan Shi, C. B. Simmons, Daniel R. Ward +9
A fundamental goal in the manipulation of quantum systems is the achievement of many coherent oscillations within the characteristic dephasing time T2*[1]. Most manipulations of el…
Coherent Quantum Oscillations in a Silicon Charge Qubit
Zhan Shi, C. B. Simmons, Daniel. R. Ward +10
Fast quantum oscillations of a charge qubit in a double quantum dot fabricated in a Si/SiGe heterostructure are demonstrated and characterized experimentally. The measured inhomoge…
