Superconducting circuits are a promising platform to realize optomechanics with a flexible design and precise control.
To date however, realizing optomechanical lattices has been compounded by the limited scaling in contemporary circuit optomechanics.
Here we overcome this challenge and realize superconducting circuit optomechanical lattices.
We demonstrate non-trivial topological modes in a 10 site optomechanical chain as well as a 24 site honeycomb lattice, realizing the Su-Schrieffer-Heeger model.
Furthermore, we present a technique exploiting embedded optomechanical interaction to directly measure the modeshape, without using any local probe.
Our new platform and measurement technique offers an avenue to explore many-body physics in optomechanical lattices.
