Holonomic quantum gates via continuous measurement in bosonic codes: GKP and cat states
An arXiv preprint proposes a scheme for holonomic quantum gates driven by continuous measurement in bosonic error-correcting codes, specifically GKP and cat states. The work is theoretical and develops geometric gate constructions that could be robust to certain control errors. No experimental demonstration is reported.

The proposal could be translated into an experimental demonstration of continuous-measurement-driven holonomic gates on superconducting cavity GKP or cat qubits within two years.
Superconducting circuit QED groups already operate GKP and cat states with high-fidelity measurement and feedback, and the gate scheme appears compatible with those existing platforms, making a proof-of-principle feasible with current hardware.
