Spin models are the prime example of simplified many-body Hamiltonians used to model
complex, strongly correlated real-world materials. However, despite the simplified character …

By mapping the strong interaction between Rydberg excitations in ultra-cold atomic
ensembles onto single photons via electromagnetically induced transparency, it is now …

The strong interaction between individual Rydberg atoms provides a powerful tool exploited
in an ever-growing range of applications in quantum information science, quantum …

Mapping the strong interaction between Rydberg atoms onto single photons via
electromagnetically induced transparency enables manipulation of light at the single-photon …

One of the critical elements in the realization of the quantum internet are deterministic two-
photon gates. This CZ photonic gate also completes a set of universal gates for all-optical …

We study a system of atoms that are laser driven to n D 3/2 Rydberg states and assess how
accurately they can be mapped onto spin-1/2 particles for the quantum simulation of …

We report on the realization of a free-space single-photon absorber, which deterministically
absorbs exactly one photon from an input pulse. Our scheme is based on the saturation of …

We investigate the optical Kerr nonlinearities of an ensemble of cold Rydberg atoms under
the condition of electromagnetically induced transparency (EIT). By using an approach …

We present an extension of our recent paper [Bienias et al., Phys. Rev. A 90, 053804 (2014)]
in which we demonstrated the scattering properties and bound-state structure of two …

We experimentally characterize the optical nonlinear response of a cold atomic medium
placed inside an optical cavity, and excited to Rydberg states. The excitation to S and D …
