Active Learning for Calibrating Entangling Gates via Surrogate-Based Optimization
Caleb Walton, Patricia García-Caspueñas, Filippo Zacchei +3
The fidelity of a quantum gate is sensitive to small deviations in the physical control parameters. Unfortunately, it is generally difficult to exactly model the implemented Hamilt…

Crosstalk Insensitive Trapped-Ion Entanglement through Coupling Matrix Engineering
Vikram Kashyap, Caleb Walton, Sara Mouradian
Optical crosstalk due to imperfect addressing in trapped-ion entangling gates generates unwanted non-local entanglement between target ions and their neighbors that is difficult to…
