Benchmarking exchange-only control of a 48-spin singlet manifold
HRL Quantum Team, Microsoft Collaborators, : +125
Exchange-only quantum computing benefits from high fidelity and straightforward control afforded by the exchange interaction. However, independently controllable qubits must be enc…
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…
Full-permutation dynamical decoupling in triple-quantum-dot spin qubits
Bo Sun, Teresa Brecht, Bryan Fong +20
Dynamical decoupling of spin qubits in silicon can enhance fidelity and be used to extract the frequency spectra of noise processes. We demonstrate a full-permutation dynamical dec…
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…
Fast and high-fidelity state preparation and measurement in triple-quantum-dot spin qubits
Jacob Z. Blumoff, Andrew S. Pan, Tyler E. Keating +19
We demonstrate rapid, high-fidelity state preparation and measurement in exchange-only Si/SiGe triple-quantum-dot qubits. Fast measurement integration ( ns) and initialization…
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…
Quantum nondemolition measurement of mechanical squeezed state beyond the 3 dB limit
C. U. Lei, A. J. Weinstein, J. Suh +5
We use a reservoir engineering technique based on two-tone driving to generate and stabilize a quantum squeezed state of a micron-scale mechanical oscillator in a microwave optomec…
Quantum squeezing of motion in a mechanical resonator
E. E. Wollman, C. U. Lei, A. J. Weinstein +5
As a result of the quantum, wave-like nature of the physical world, a harmonic oscillator can never be completely at rest. Even in the quantum ground state, its position will alway…
Observation and interpretation of motional sideband asymmetry in a quantum electro-mechanical device
A. J. Weinstein, C. U. Lei, E. E. Wollman +4
Quantum electro-mechanical systems offer a unique opportunity to probe quantum noise properties in macroscopic devices, properties which ultimately stem from the Heisenberg Uncerta…
Mechanically Detecting and Avoiding the Quantum Fluctuations of a Microwave Field
J. Suh, A. J. Weinstein, C. U. Lei +5
During the theoretical investigation of the ultimate sensitivity of gravitational wave detectors through the 1970's and '80's, it was debated whether quantum fluctuations of the li…
