Abstract

Although mechanical oscillators play pivotal roles in modern science and technology, their application to quantum technology remains challenging. The advent of cavity optomechanics marks a significant breakthrough. In particular, superconducting circuit optomechanics at cryogenic temperatures serves as a pioneering platform for the quantum control and measurement of mechanical oscillators. By introducing an innovative fabrication technique, we have overcome the long-lasting challenges in this field and realized long-lived and scalable superconducting circuit optomechanics operating at the quantum limit. Our systems not only offer a novel framework for many-body physics research but also provide solutions for quantum memory in quantum computing and communication. Additionally, they hold promise for fundamental physics research, including the observation of macroscopic quantum effects and the search for dark matter.
