Empirical learning of dynamical decoupling on quantum processors
Christopher Tong, Helena Zhang, Bibek Pokharel
Dynamical decoupling (DD) is a low-overhead method for quantum error suppression. Despite extensive work in DD design, finding pulse sequences that optimally decouple computational…

Machine Learning based Discrimination for Excited State Promoted Readout
Utkarsh Azad, Helena Zhang
A limiting factor for readout fidelity for superconducting qubits is the relaxation of the qubit to the ground state before the time needed for the resonator to reach its final tar…

Parallel Position-Controlled Composite Quantum Logic Gates with Trapped Ions
Michael S. Gutierrez, Guang Hao Low, Richard Rines +1
We demonstrate parallel composite quantum logic gates with phases implemented locally through nanoscale movement of ions within a global laser beam of fixed pulse duration. We show…
