Abstract

The influence of an optical nanofiber on the spontaneous emission rates and Lamb shifts of a Rydberg rubidium atom in its close vicinity is investigated, in view of the implementation of a Rydberg-blockade-based quantum network.

Spontaneous emission and energy shifts of a Rydberg rubidium atom close to an optical nanofiber

Erwan Stourm, Maxence Lepers, Jacques Robert +3 more

In this paper, we report on numerical calculations of the spontaneous emission rates and Lamb shifts of a $^{87}\mathrm{Rb}$ atom in a Rydberg-excited state $\left(n\ensuremath{\le}30\right)$ located close to a silica optical nanofiber. We investigate how these quantities depend on the fiber's radius, the distance of the atom to the fiber, the direction of the atomic angular momentum polarization, as well as the different atomic quantum numbers. We also study the contribution of quadrupolar transitions, which may be substantial for highly polarizable Rydberg states. Our calculations are performed in the macroscopic quantum electrodynamics formalism, based on the dyadic Green's function method. This allows us to take dispersive and absorptive characteristics of silica into account; this is of major importance since Rydberg atoms emit along many different transitions whose frequencies cover a wide range of the electromagnetic spectrum. Our work is an important initial step toward building a Rydberg atom-nanofiber interface for quantum optics and quantum information purposes.

Rydberg atoms in the vicinity of an optical nanofiber

Erwan Stourm, Maxence Lepers, Jacques Robert +3 more

Highly excited (so-called Rydberg) atoms are the key ingredient of many quantum information schemes. In this presentation, we shall theoretically investigate how spontaneous emission properties and van der Waals interactions of such atoms are modified in the neighbourhood of an optical nanofiber with respect to the free-space (vacuum) case. This work constitutes a very preliminary step towards the realization of a quantum network based on atomic ensembles linked via optical nanofibers.

Spontaneous emission of a sodium Rydberg atom close to an optical nanofibre

Erwan Stourm, Y Zhang, Maxence Lepers +5 more

We report on numerical calculations of the spontaneous emission rate of a Rydberg-excited sodium atom in the vicinity of an optical nanofibre. In particular, we study how this rate varies with the distance of the atom to the fibre, the fibre's radius, the symmetry s or p of the Rydberg state as well as its principal quantum number. We find that a fraction of the spontaneously emitted light can be captured and guided along the fibre. This suggests that such a setup could be used for networking atomic ensembles, manipulated in a collective way due to the Rydberg blockade phenomenon.

We discuss work on the integration of optical nanofibers with cold atoms. We focus on two aspects, one related to Rydberg atom formation mediated by the nanofiber and the other to optimizing atom trapping.
