Subwavelength atomic lattices have been established as a promising platform for quantum applications, utilizing collective superradiant and subradiant behavior to enhance atom-light interactions. While previous work has demonstrated high-fidelity atom-photon entanglement in these systems, the generation of atom–atom entanglement, crucial ingredient full scalability, remains conceptual challenge. Here, we propose methods between qubits by identifying specific atoms within ring array qubits. The is achieved excitation involving both states leveraging novel symmetry properties array. Specifically, utilize breaking preparing superpositions detunings our protocols. A fidelity analysis protocols provides practical experimental parameters state-of-the-art setups.

The Stark effect provides a powerful method to shift the spectra of molecules, atoms, and electronic transitions in general, becoming one simplest most straightforward ways tune frequency quantum emitters by means static electric field. At same time, order reduce emitter sensitivity charge noise, inversion symmetric systems are typically designed, providing stable emission with quadratic-only dependence on applied However, such nonlinear behavior might be reflected correlations between tuning ability unwanted spectral fluctuations. Here, we provide experimental evidence this trend using molecular solid state cooled down liquid helium temperatures. We finally combine field generated electrodes, which is parallel molecule's induced dipole, optically excite long-lived states acting perpendicular direction. Based anisotropy polarizability, our two-dimensional control local allows us not only emitter's but also sensibly suppress instabilities associated
