The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Here, we demonstrate a release-free electro-optomechanical transducer combining strong optomechanical interactions in silicon with the efficient piezoelectricity of lithium niobate via micro-transfer printing. We observe electro- and optomechanical coupling rates compatible with quantum-level operation when co-integrated with a superconducting microwave circuit.

C2weakest assumption

That micro-transfer printing successfully bonds the materials without introducing significant optical or mechanical losses or degrading the optomechanical coupling, and that the observed rates truly reach the quantum regime without detailed supporting data or error analysis provided.

C3one line summary

A release-free electro-optomechanical transducer is demonstrated with electro- and optomechanical coupling rates compatible with quantum-level operation.
