Qubit ZooDemonstrates a circuit-QED quantum bus that coherently transfers states between two superconducting qubits on opposite sides of a chip using virtual photons in a shared transmission-line cavity.
Key Results
- First coherent cavity-bus coupling of spatially separated superconducting qubits.
- Virtual-photon exchange avoids populating the lossy cavity during the mediated interaction.
- The same cavity supports multiplexed qubit control and measurement.
