Multipartite controlled-NOT gates using molecules and Rydberg atoms

Multi-qubit quantum gates offer an effcient pathway to reducing circuit depth in quantum information processing. Here, we propose two multipartite controlled-NOT gate schemes in a hybrid platform composed of polar molecules and Rydberg atoms. By encoding the control qubits in the long-lived ground states of polar molecules and harnessing the strong dipole-dipole interactions of Rydberg atoms, our approach establishes a gate mechanism that enables both strong and controllable coupling while effectively suppressing decoherence. The scheme can be naturally generalized to larger systems, providing a scalable route toward hybrid quantum computation.
