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…
Two-dimensional Si spin qubit arrays with multilevel interconnects
Sieu D. Ha, Edwin Acuna, Kate Raach +26
The promise of quantum computation is contingent upon physical qubits with both low gate error rate and broad scalability. Silicon-based spins are a leading qubit platform, but dem…
Ultra-dispersive resonator readout of a quantum-dot qubit using longitudinal coupling
Benjamin Harpt, J. Corrigan, Nathan Holman +10
We perform readout of a quantum-dot hybrid qubit coupled to a superconducting resonator through a parametric, longitudinal interaction mechanism. Our experiments are performed with…
Longitudinal coupling between a Si/SiGe quantum dot and an off-chip TiN resonator
J. Corrigan, Benjamin Harpt, Nathan Holman +10
Superconducting cavities have emerged as a key tool for measuring the spin states of quantum dots. So far however, few experiments have explored longitudinal couplings between dots…
How valley-orbit states in silicon quantum dots probe quantum well interfaces
J. P. Dodson, H. Ekmel Ercan, J. Corrigan +7
The energies of valley-orbit states in silicon quantum dots are determined by an as yet poorly understood interplay between interface roughness, orbital confinement, and electron i…
Dispersive measurement of a semiconductor double quantum dot via 3D integration of a high-impedance TiN resonator
Nathan Holman, D. Rosenberg, D. Yost +5
Spins in semiconductor quantum dots are a candidate for cryogenic quantum processors due to their exceptionally long coherence times. One major challenge to scaling quantum dot spi…
