Improving Raman Gate Fidelity via Pulse Shaping and Integrated Photonics for Trapped Ion Quantum Computing
Isaac L. Chuang
For this SuperUROP project, we are interested in actualizing a two-qubit gate using Raman transitions in a pair of calcium ions. In particular, we will investigate how laser pulse-shaped sequences and integrated photonic beam delivery affect gate fidelity at high speeds.
We expect that by smoothing-out the pulses used to realize the two-qubit gate, we will be able to mitigate the infidelity that arises when said gates are driven quickly. Additionally, by delivering the Raman beams through wave guides in a micro-fabricated ion trap, we may be able to control the optical phase between the beams, resulting in possibly higher fidelities.
Through these improvements to the Raman laser pulses and beam delivery method, we hope to demonstrate a quantum gate at record speeds and fidelities.
After working in the Quanta Lab on projects related to lab automation, pulse shaping, and the theory of two-qubit gates, I am eager to take my research contributions to the next level via SuperUROP. I am especially excited to have the structure of this program insofar as learning about research techniques and presentation, whilst also having the liberty to explore questions at the intersection of atomic physics and electrical engineering.
