Cavity Detection with Single Atom Array
Abstract: We place single Rubidium atoms inside of a high-finesse optical cavity using optical tweezer array. This allows us to: 1. Characterize the dichromatic cavity modes profile using fluorescent single atoms as scanning probes. We demonstrate beyond diffraction limit resolution microscopy of the cavity mode axial and radial patterns. 2. Sequential state measurement of single atoms with high fidelity and fast speed while maintaining the state coherence of the rest of the atom array. We present this as a means of mid-quantum-circuit measurement protocol, an essential building block for atom array quantum computing. 3. Position multiple atoms inside the cavity mode in spatial patterns that exhibit super/sub-radiance under side pumping, and searching for self-organization of the atom array under Dicke-state-like spontaneous symmetry breaking.
