- Abstract summary: We propose a robust localization of the highly-excited Rydberg atoms, interacting with doughnut-shaped optical vortices.
A vortex beam can provide an ultrahigh-precision two-dimensional localization solely in the zero-intensity center.
To develop a new subwavelength localization technique, our results pave one-step closer to reduce excitation volumes to the level of a few nanometers.

- Abstract: We propose a robust localization of the highly-excited Rydberg atoms,
interacting with doughnut-shaped optical vortices. Compared with the earlier
standing-wave (SW)-based localization methods, a vortex beam can provide an
ultrahigh-precision two-dimensional localization solely in the zero-intensity
center, within a confined excitation region down to the nanometer scale. We
show that the presence of the Rydberg-Rydberg interaction permits
counter-intuitively much stronger confinement towards a high spatial resolution
when it is partially compensated by a suitable detuning. In addition, applying
an auxiliary SW modulation to the two-photon detuning allows a
three-dimensional confinement of Rydberg atoms. In this case, the vortex field
provides a transverse confinement while the SW modulation of the two-photon
detuning localizes the Rydberg atoms longitudinally. To develop a new
subwavelength localization technique, our results pave one-step closer to
reduce excitation volumes to the level of a few nanometers, representing a
feasible implementation for the future experimental applications.

spatial modes of light provide a high-dimensional space that can be used to encode both classical and quantum information.
Current approaches for dynamically generating and measuring these modes are slow, due to the need to reconfigure a high-resolution phase mask.
We experimentally realize this approach, using a double-pass AOM to generate one of five orbital angular momentum states.
We are able to reconstruct arbitrary states in under 1 ms with an average fidelity of 96.9%.

We generate highly entangled photon pairs at telecom wavelength that we characterise via two-photon interference and quantum state tomography, achieving near-unity visibilities and fidelities.
