Single-Shot Readout Performance of Two Heterojunction-Bipolar-Transistor Amplification Circuits at Millikelvin Temperatures
M. J. Curry, M. Rudolph, T. D. England +12
High-fidelity single-shot readout of spin qubits requires distinguishing states much faster than the T1 time of the spin state. One approach to improving readout fidelity and bandw…
All-electrical universal control of a double quantum dot qubit in silicon MOS
Patrick Harvey-Collard, Ryan M. Jock, N. Tobias Jacobson +12
Qubits based on transistor-like Si MOS nanodevices are promising for quantum computing. In this work, we demonstrate a double quantum dot spin qubit that is all-electrically contro…
Ion Implantation for Deterministic Single Atom Devices
J. L. Pacheco, M. Singh, D. L. Perry +8
We demonstrate a capability of deterministic doping at the single atom level using a combination of direct write focused ion beam and solid-state ion detectors. The focused ion bea…
Quantum dots with split enhancement gate tunnel barrier control
S. Rochette, M. Rudolph, A. -M. Roy +10
We introduce a silicon metal-oxide-semiconductor quantum dot architecture based on a single polysilicon gate stack. The elementary structure consists of two enhancement gates separ…
High-fidelity single-shot readout for a spin qubit via an enhanced latching mechanism
Patrick Harvey-Collard, Benjamin D'Anjou, Martin Rudolph +9
The readout of semiconductor spin qubits based on spin blockade is fast but suffers from a small charge signal. Previous work suggested large benefits from additional charge mappin…
Fabrication of quantum dots in undoped Si/SiGe heterostructures using a single metal-gate layer
T. M. Lu, J. K. Gamble, R. P. Muller +9
Enhancement-mode Si/SiGe electron quantum dots have been pursued extensively by many groups for \revEdit{their} potential in quantum computing. Most of the reported dot designs uti…
