A superconducting qubit in a slow waveguide localises and binds photons around itself.

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...
