Controllable Switching between Superradiant and Subradiant States in a 10-qubit Superconducting Circuit
Controllable Switching between Superradiant and Subradiant States in a 10-qubit Superconducting Circuit
Superradiance and subradiance concerning enhanced and inhibited collective radiation of an ensemble of atoms have been a central topic in quantum optics. However, precise generation and control of these states remain challenging. Here we deterministically generate up to 10-qubit superradiant and 8-qubit subradiant states, each containing a single excitation, in …
