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…
