Creating detailed computer models of quantum chips helps scientists predict how they will behave before manufacturing begins. This approach allows researchers to catch potential issues early and confirm that designs will perform as expected. At Berkeley Lab, Quantum Systems Accelerator (QSA) researchers Zhi Jackie Yao and Andy Nonaka from the Applied Mathematics and Computational Research (AMCR) Division are building advanced electromagnetic simulations to support the development of next-generation quantum hardware.
“The computational model predicts how design decisions affect electromagnetic wave propagation in the chip,” said Nonaka, “to make sure proper signal coupling occurs and avoid unwanted crosstalk.”
To carry out this work, the team used ARTEMIS, an exascale…
