• Abstract summary: We demonstrate single-shot and textitin situ absorption imaging of individual Rydberg superatoms. With an exposure time as short as 3 $mu$s, we successfully resolve linear chains of Rydberg superatoms excited in a one-dimensional configuration. This technique, with minimal destruction, will be of great interest for leveraging ensemble-encoded qubits in quantum computation and quantum simulation applications.

• Abstract: We demonstrate single-shot and \textit{in situ} absorption imaging of individual Rydberg superatoms. This level of resolution is achieved using an electromagnetically induced transparency scheme involving a Rydberg energy level that is highly sensitive to the presence of Rydberg superatoms due to F\"{o}rster-resonance-enhanced dipole couplings. Spectroscopic measurements illustrate the existence of the F\"{o}rster resonance and underscore the state-selectivity of the technique. With an imaging exposure time as short as 3 $\mu$s, we successfully resolve linear chains of Rydberg superatoms excited in a one-dimensional configuration. The extracted second-order correlation shows strong anti-bunching due to excitation blockade, and a Fourier analysis reveals the long-range order in the chains of Rydberg superatoms. This imaging technique, with minimal destruction, will be of great interest for leveraging ensemble-encoded qubits in quantum computation and quantum simulation applications.

  Rydberg states of excitons are promising quantum objects to engineer giant nonlinearities in a solid-state system. We report experimental results where two-photon absorption is resonant with various Rydberg states of excitons in copper oxide. We observe several intriguing dynamics including the presence of long-lived coherent oscillations.

• Avalanche terahertz photon detection in a Rydberg tweezer array [0.0]
  We propose a protocol for the amplified detection of low-intensity terahertz radiation using Rydberg tweezer arrays. During a sensing phase, it harnesses strong terahertz-range transitions between highly excited Rydberg states to capture individual terahertz photons. During an amplification phase, it exploits the Rydberg facilitation mechanism which converts a single terahertz photon into a substantial signal of Rydberg excitations.

  Two non-identical quantum emitters, when placed within a cavity and coherently excited at the two-photon resonance, can reach stationary states of nearly maximal entanglement. We show that this mechanism is merely one among a complex family of phenomena that can generate both stationary and metastable entanglement when driving the emitters at the two-photon resonance.
