In the future, quantum computers could rapidly simulate new materials or help scientists develop faster machine‐learning models, opening the door to many new possibilities.

The researchers used a novel superconducting circuit architecture to show nonlinear light‐matter coupling that is about an order of magnitude stronger than prior demonstrations, which could enable a quantum processor to run about 10 times faster.

There is still much work to be done before the architecture could be used in a real quantum computer, but demonstrating the fundamental physics behind the process is a major step in the right direction, says Yufeng “Bright” Ye Ph.D., lead author of a paper on this research.

“This would really eliminate one of the bottlenecks in quantum computing. Usually, you have to measure the results of your computations in between rounds of error correction. This could accelerate how quickly we can reach the fault‐tolerant quantum computing stage and be able to get real‐world applications and value out of our quantum computers,” says Ye.
