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…
Universal logic with encoded spin qubits in silicon
Aaron J. Weinstein, Matthew D. Reed, Aaron M. Jones +20
Qubits encoded in a decoherence-free subsystem and realized in exchange-coupled silicon quantum dots are promising candidates for fault-tolerant quantum computing. Benefits of this…
A flexible design platform for Si/SiGe exchange-only qubits with low disorder
Wonill Ha, Sieu D. Ha, Maxwell D. Choi +14
Spin-based silicon quantum dots are an attractive qubit technology for quantum information processing with respect to coherence time, control, and engineering. Here we present an e…
Optimization of Quantum-dot Qubit Fabrication via Machine Learning
Antonio B. Mei, Ivan Milosavljevic, Amanda L. Simpson +6
Precise nanofabrication represents a critical challenge to developing semiconductor quantum-dot qubits for practical quantum computation. Here, we design and train a convolutional…
Magnetic Gradient Fluctuations from Quadrupolar Ge in Si/SiGe Exchange-Only Qubits
J. Kerckhoff, B. Sun, B. H. Fong +14
We study the time-fluctuating magnetic gradient noise mechanisms in pairs of Si/SiGe quantum dots using exchange echo noise spectroscopy. We find through a combination of spectral…
Quantifying error and leakage in an encoded Si/SiGe triple-dot qubit
R. W. Andrews, C. Jones, M. D. Reed +13
Quantum computation requires qubits that satisfy often-conflicting criteria, including scalable control and long-lasting coherence. One approach to creating a suitable qubit is to…
Spin-Blockade Spectroscopy of Si/SiGe Quantum Dots
A. M. Jones, E. J. Pritchett, E. H. Chen +15
We implement a technique for measuring the singlet-triplet energy splitting responsible for spin-to-charge conversion in semiconductor quantum dots. This method, which requires fas…
