I completed a summer internship (Summer 2023) at IBM Quantum where I worked on the development of novel quantum gates aimed at improving the ability to manipulate qubits. I applied methods from optimal control theory to numerically engineer microwave pulses robust against unwanted perturbations. While such gates are designed to improve gate fidelity, their actual experimental performance inevitably falls short due the disconnect between the large-parameter space typical of numerically designed gates and the scalability requirements of experimental gate calibration. To address this challenge, our team developed a closed-loop, model-free calibration procedure tune-up the gates on real IBM quantum hardware and bring their actual performance in line with their intended performance.

I wrote a first-author paper detailing this work (under review at Phys. Rev. Res.): https://arxiv.org/abs/2412.05230
