Gate-Sensing Charge Pockets in the Semiconductor Qubit Environment
X. G. Croot, S. J. Pauka, H. Lu +6
We report the use of dispersive gate sensing (DGS) as a means of probing the charge environment of heterostructure-based qubit devices. The DGS technique, which detects small shift…
Cryogenic Control Architecture for Large-Scale Quantum Computing
J. M. Hornibrook, J. I. Colless, I. D. Conway Lamb +8
Solid-state qubits have recently advanced to the level that enables them, in-principle, to be scaled-up into fault-tolerant quantum computers. As these physical qubits continue to…
Frequency Multiplexing for Readout of Spin Qubits
J. M. Hornibrook, J. I. Colless, A. C. Mahoney +5
We demonstrate a low loss, chip-level frequency multiplexing scheme for readout of scaled-up spin qubit devices. By integrating separate bias tees and resonator circuits on-chip fo…
Stimulated Phonon Emission in a Driven Double Quantum Dot
J. I. Colless, X. G. Croot, T. M. Stace +5
The compound semiconductor gallium arsenide (GaAs) provides an ultra-clean platform for storing and manipulating quantum information, encoded in the charge or spin states of electr…
Ultra-fast transistor-based detectors for precise timing of near infrared and THz signals
S. Preu, M. Mittendorff, S. Winnerl +3
A whole class of two-color experiments involves intense, short Terahertz radiation pulses. A fast detector that is sensitive and able to resolve both near-infrared and Terahertz pu…
Landau-Zener-Stuckelberg Interferometry of a Single Electron Charge Qubit
J. Stehlik, Y. Dovzhenko, J. R. Petta +4
We perform Landau-Zener-Stuckelberg interferometry on a single electron GaAs charge qubit by repeatedly driving the system through an avoided crossing. We observe coherent destruct…
