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…
A digitally controlled silicon quantum processing unit
Members of the HRL Quantum Team, Collaborators, : +255
Commercially-relevant quantum computers will require large numbers of high-performing qubits that can be manufactured, integrated, and controlled at scale. Silicon exchange-only (E…
Direct integration of atomic precision advanced manufacturing into middle-of-line silicon fabrication
E. M. Anderson, C. R. Allemang, A. J. Leenheer +13
Atomic precision advanced manufacturing (APAM) dopes silicon with enough carriers to change its electronic structure and can be used to create novel devices by defining metallic re…
On-chip cryogenic multiplexing of Si/SiGe quantum devices
M. A. Wolfe, Thomas McJunkin, Daniel R. Ward +3
The challenges of operating qubits in a cryogenic environment point to a looming bottleneck for large-scale quantum processors, limited by the number of input-output connections. C…
A programmable two-qubit quantum processor in silicon
T. F. Watson, S. G. J. Philips, E. Kawakami +9
With qubit measurement and control fidelities above the threshold of fault-tolerance, much attention is moving towards the daunting task of scaling up the number of physical qubits…
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…
Valley dependent anisotropic spin splitting in silicon quantum dots
Rifat Ferdous, Erika Kawakami, Pasquale Scarlino +9
Spin qubits hosted in silicon (Si) quantum dots (QD) are attractive due to their exceptionally long coherence times and compatibility with the silicon transistor platform. To achie…
Two-axis control of a singlet-triplet qubit with an integrated micromagnet
Xian Wu, D. R. Ward, J. R. Prance +9
The qubit is the fundamental building block of a quantum computer. We fabricate a qubit in a silicon double quantum dot with an integrated micromagnet in which the qubit basis stat…
Fast coherent manipulation of three-electron states in a double quantum dot
Zhan Shi, C. B. Simmons, Daniel R. Ward +9
A fundamental goal in the manipulation of quantum systems is the achievement of many coherent oscillations within the characteristic dephasing time T2*[1]. Most manipulations of el…
Integration of on-chip field-effect transistor switches with dopantless Si/SiGe quantum dots for high-throughput testing
Daniel R. Ward, D. E. Savage, M. G. Lagally +2
Measurement of multiple quantum devices on a single chip increases characterization throughput and enables testing of device repeatability, process yield, and systematic variations…
