Nanofabricated quantum bits permit large-scale integration but usually  suffer from short coherence times due to interactions with their  solid-state environment.  The outstanding challenge is to engineer the environment so that it  minimally affects the qubit, but still allows qubit control and  scalability. In their article, published in Nature Nanotechnology on August 10, 2014, Casimir PhD students Erika Kawakami and Pasquale Scarlino, QT-alumnus dr. Floris Braakman, professor Lieven Vandersypen (et al.) demonstrate a long-lived single-electron spin  qubit in a Si/SiGe quantum dot with all-electrical two-axis control.
