Realization and Calibration of Continuously Parameterized Two-Qubit Gates on a Trapped-Ion Quantum Processor
Christopher G. Yale, Ashlyn D. Burch, Matthew N. H. Chow +5
Continuously parameterized two-qubit gates are a key feature of state-of-the-art trapped-ion quantum processors as they have favorable error scalings and show distinct improvements…
Solovay Kitaev Algorithm and Randomized Compilation
Oliver Maupin, Ashlyn D. Burch, Christopher G. Yale +10
We analyze the use of the Solovay Kitaev (SK) algorithm to generate an ensemble of one qubit rotations over which to perform randomized compilation. We perform simulations to compa…
Noise-Aware Circuit Compilations for a Continuously Parameterized Two-Qubit Gateset
Christopher G. Yale, Rich Rines, Victory Omole +9
State-of-the-art noisy-intermediate-scale quantum (NISQ) processors are currently implemented across a variety of hardware platforms, each with their own distinct gatesets. As such…
