Error-robust quantum logic optimization using a cloud quantum computer interface
Andre R. R. Carvalho, Harrison Ball, Michael J. Biercuk +2
We describe an experimental effort designing and deploying error-robust single-qubit operations using a cloud-based quantum computer and analog-layer programming access. We design…
Quantum oscillator noise spectroscopy via displaced cat states
Alistair R. Milne, Cornelius Hempel, Li Li +5
Quantum harmonic oscillators are central to many modern quantum technologies. We introduce a method to determine the frequency noise spectrum of oscillator modes through coupling t…
Numeric optimization for configurable, parallel, error-robust entangling gates in large ion registers
Christopher D. B. Bentley, Harrison Ball, Michael J. Biercuk +3
We study a class of entangling gates for trapped atomic ions and demonstrate the use of numeric optimization techniques to create a wide range of fast, error-robust gate constructi…
Software tools for quantum control: Improving quantum computer performance through noise and error suppression
Harrison Ball, Michael J. Biercuk, Andre Carvalho +10
Manipulating quantum computing hardware in the presence of imperfect devices and control systems is a central challenge in realizing useful quantum computers. Susceptibility to noi…
Site-resolved imaging of beryllium ion crystals in a high-optical-access Penning trap with inbore optomechanics
Harrison Ball, Christian D. Marciniak, Robert N. Wolf +3
We present the design, construction and characterization of an experimental system capable of supporting a broad class of quantum simulation experiments with hundreds of spin qubit…
Measuring and Suppressing Error Correlations in Quantum Circuits
C. L. Edmunds, C. Hempel, R. Harris +4
Quantum error correction provides a path to large-scale quantum computers, but is built on challenging assumptions about the characteristics of the underlying errors. In particular…
