Improving capacitors in circuit QED is key to achieving longer-lived and scalable elements. When combined with mechanical functionality, vacuum-gap capacitors open new possibilities for hybrid quantum systems.

High-kinetic inductance materials enable compact superinductors and nonlinear elements—but how reproducible are they? Can we measure the disorder? Is it low enough to build scalable multimode systems? Find out in our latest

Great start to April with a new publication in
npj Quantum Information! In a simple SQUID array resonator, we show Landau-Zener transitions across the qubit, linear, and multiphoton regimes. With the signature of dissipative quantum chaos with many photons. Take a look: nature.com/articles/s41...

Excited to share that our latest work is now published in
PRX quantum! We explore quantum sensing beyond linear scaling in superconducting circuits by leveraging critical phenomena. Check it out: journals.aps.org/prxquantum/a...
