If the Cat Bus can be implemented with existing superconducting technology, it could enable a demonstration of a logical qubit with reduced overhead within two years.
Cat codes are already being explored in superconducting circuits; a bus architecture might leverage multimode cavities to simplify error correction, potentially accelerating logical qubit demonstrations.
