This could enable near-term simulation of larger Z2 lattice gauge theories by using oscillator modes to encode gauge fields, reducing qubit overhead and allowing experiments on confinement or topological order that are currently difficult on all-qubit superconducting processors.
Hybrid qubit–oscillator platforms already exist in superconducting circuit QED, and the demonstration validates coherent control of a gauge field in an oscillator. Scaling to a few more sites requires ordinary engineering, though it is gated on maintaining coherence and implementing multi-site gauge-invariant operations, which is plausible within the next two years.
