Magnetic gradient free two axis control of a valley spin qubit in SiGe
Y. -Y. Liu, L. A. Orona, Samuel F. Neyens +3
Spins in SiGe quantum dots are promising candidates for quantum bits but are also challenging due to the valley degeneracy which could potentially cause spin decoherence and weak s…
Radio frequency reflectometry in silicon-based quantum dots
Y. -Y. Liu, S. G. J. Philips, L. A. Orona +6
RF reflectometry offers a fast and sensitive method for charge sensing and spin readout in gated quantum dots. We focus in this work on the implementation of RF readout in accumula…
Microwave detection of electron-phonon interactions in a cavity-coupled double quantum dot
T. R. Hartke, Y. -Y. Liu, M. J. Gullans +1
Quantum confinement leads to the formation of discrete electronic states in quantum dots. Here we probe electron-phonon interactions in a suspended InAs nanowire double quantum dot…
Phase locking of a semiconductor double quantum dot single atom maser
Y. -Y. Liu, T. Hartke, J. Stehlik +1
We experimentally study the phase stabilization of a semiconductor double quantum dot (DQD) single atom maser by injection locking. A voltage-biased DQD serves as an electrically t…
Threshold Dynamics of a Semiconductor Single Atom Maser
Y. -Y. Liu, J. Stehlik, C. Eichler +5
We demonstrate a single-atom maser consisting of a semiconductor double quantum dot (DQD) that is embedded in a high quality factor microwave cavity. A finite bias drives the DQD o…
Double Quantum Dot Floquet Gain Medium
J. Stehlik, Y. -Y. Liu, C. Eichler +5
Strongly driving a two-level quantum system with light leads to a ladder of Floquet states separated by the photon energy. Nanoscale quantum devices allow the interplay of confined…
