Research Project Title:
Minimizing Crosstalk in Superconducting Circuit Quantum Processor Design
abstract:Superconducting circuits are one of the leading modalities for quantum information processing. While quantum processors exist, their size is limited by noise. Reducing noise is key to scaling up to more powerful devices. One major source of noise is crosstalk between the qubit control lines. In our current devices, two separate lines are used to control each qubit. This leads to crowded designs with complicated wire-routing schemes that are prone to crosstalk. Crosstalk between the two lines is particularly pernicious because it is difficult to characterize. Through simulations, we will quantify expected crosstalk and improve design to minimize its effects. Ultimately, we would like to demonstrate a new design that minimizes crosstalk on multi-qubit devices
"I am excited about this project as it provides me the opportunity to do research on improving our abilities to do large-scale quantum computation, one of the great technological challenges facing society today. Personally, I also find it an intellectually stimulating field, and I am happy I get to apply the skills I have acquired in both of my majors, EECS and physics."
