Predicting the Slow Drift of Nuclear Spin Noise in Semiconductor Spin Qubits
Wayne M. Witzel, Jesse J. Lutz, Matthew D. Grace +3
The dynamics of a nuclear spin bath generates magnetic noise that is a key contributor to the decoherence of electron spin qubits in electrostatically-defined quantum dots. In this…
Anisotropic spin-valley coupling in SiMOS and Si/SiGe quantum dots
N. Tobias Jacobson, Natalie D. Foster, Ryan M. Jock +5
While bulk silicon has long been understood to exhibit relatively weak spin-orbit coupling (SOC), confinement of electrons to quantum dots (QDs) at a silicon heterointerface result…
3D tomography of exchange phase in a Si/SiGe quantum dot device
Dylan Albrecht, Sarah Thompson, N. Tobias Jacobson +1
The exchange interaction is a foundational building block for the operation of spin-based quantum processors. Extracting the exchange interaction coefficient , as a…
Dephasing and error dynamics affecting a singlet-triplet qubit during coherent spin shuttling
Natalie D. Foster, Jacob D. Henshaw, Martin Rudolph +2
Quantum information transport over micron to millimeter scale distances is critical for the operation of practical quantum processors based on spin qubits. One method of achieving…
A silicon singlet-triplet qubit driven by spin-valley coupling
Ryan M. Jock, N. Tobias Jacobson, Martin Rudolph +3
Spin-orbit effects, inherent to electrons confined in quantum dots at a silicon heterointerface, provide a means to control electron spin qubits without the added complexity of on-…
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…

Gopal Bhatta
Quasi-periodic oscillations (QPO) originating from innermost regions of blazars can provide unique perspective of some of the burning issues in blazar studies including disk-jet co…
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…
Probing low noise at the MOS interface with a spin-orbit qubit
Ryan M. Jock, N. Tobias Jacobson, Patrick Harvey-Collard +12
The silicon metal-oxide-semiconductor (MOS) material system is technologically important for the implementation of electron spin-based quantum information technologies. Researchers…
Coupling MOS Quantum Dot and Phosphorus Donor Qubit Systems
M. Rudolph, P. Harvey-Collard, R. Jock +8
Si-MOS based QD qubits are attractive due to their similarity to the current semiconductor industry. We introduce a highly tunable MOS foundry compatible qubit design that couples…
