TL;DR: Coherent control of electron spins in two coupled quantum dots in an undoped Si/SiGe heterostructure is reported and it is shown that this system has a nuclei-induced dephasing time of 360 nanoseconds, which is an increase by nearly two orders of magnitude over similar measurements in GaAs-based quantum dots.
Journal ArticleDOI
Isotopically enhanced triple-quantum-dot qubit.

TL;DR: This work demonstrates universal coherent control of a triple-quantum-dot qubit implemented in an isotopically enhanced Si/SiGe heterostructure and demonstrates sufficient control with sufficiently low noise to enable the long pulse sequences required for exchange-only two-qubit logic and randomized benchmarking.
Proceedings ArticleDOI
GaN double heterojunction field effect transistor for microwave and millimeterwave power applications
Miroslav Micovic,Paul Hashimoto,Ming Hu,Ivan Milosavljevic,J. Duvall,P. J. Willadsen,W.-S. Wong,A.M. Conway,A. Kurdoghlian,Peter W. Deelman,Jeong-S. Moon,Adele E. Schmitz,M.J. Delaney +12 more
TL;DR: In this paper, a double heterojunction field effect tansistor (DHFET) with low Al content Al/sub 0.96/N buffer layer was proposed.
Journal ArticleDOI
Sub-Micron Area Heterojunction Backward Diode Millimeter-Wave Detectors With 0.18 ${\rm pW/Hz}^{1/2}$ Noise Equivalent Power
TL;DR: InAs/AlSb/AlGaSb heterojunction backward diodes are promising detectors for millimeter-wave imaging applications due to their high sensitivity, low noise, and high cutoff frequency as mentioned in this paper.
Journal ArticleDOI
Pauli spin blockade in undoped Si/SiGe two-electron double quantum dots
Matthew Borselli,Kevin H. Eng,Edward T. Croke,Brett M. Maune,Biqin Huang,Richard S. Ross,Andrey A. Kiselev,Peter W. Deelman,Ivan Alvarado-Rodriguez,Adele E. Schmitz,Marko Sokolich,K.S. Holabird,Thomas Hazard,Mark F. Gyure,Andrew T. Hunter +14 more
TL;DR: In this paper, double quantum dots fabricated in undoped Si/SiGe heterostructures relying on a double top-gated design are shown to reliably deplete these devices to zero charge occupancy.
