“…The resonant atom-light interaction can be exploited to construct some of the most sensitive magnetometers [4] and there are prospects for magnetometers with nanometric spatial resolution using nanocells [5]. The off-resonant Faraday effect is also beneficial in, for example, achieving a narrow-bandwidth optical filter with ultrahigh background rejection (the Faraday anomalous dispersion optical filter, FADOF) with atoms [6] and crystals [7]; realizing a dichroic beam splitter for Raman light [8]; non-invasive atomic probing [9] and far off-resonance Faraday locking [10].…”

Here we report on measurements of the absolute absorption and dispersion of light in a dense rubidium vapour on the D2 line in the weak-probe regime with an applied magnetic field. A model for the electric susceptibility of the vapour is presented which includes both dipole-dipole interactions and the Zeeman effect. The predicted susceptibility is comprehensively tested by comparison to experimental spectra for fields up to 800 G. The dispersive properties of the medium are tested by comparison between experimental measurements and theoretical prediction of the Stokes parameters as a function of the atom-light detuning.

“…The second peak is relatively small compared with the first peak. This result is related to another merit of the quantum memory, which can be used as a good narrow-bandwidth filter [31]. The single photons are filtered by the filter and etalon (Figure 1) before they are sent to the quantum memory.…”

Quantum repeaters are critical components for distributing entanglement over long distances in presence of unavoidable optical losses during transmission. Stimulated by the Duan–Lukin–Cirac–Zoller protocol, many improved quantum repeater protocols based on quantum memories have been proposed, which commonly focus on the entanglement-distribution rate. Among these protocols, the elimination of multiple photons (or multiple photon-pairs) and the use of multimode quantum memory are demonstrated to have the ability to greatly improve the entanglement-distribution rate. Here, we demonstrate the storage of deterministic single photons emitted from a quantum dot in a polarization-maintaining solid-state quantum memory; in addition, multi-temporal-mode memory with 1, 20 and 100 narrow single-photon pulses is also demonstrated. Multi-photons are eliminated, and only one photon at most is contained in each pulse. Moreover, the solid-state properties of both sub-systems make this configuration more stable and easier to be scalable. Our work will be helpful in the construction of efficient quantum repeaters based on all-solid-state devices.

“…The memory crystal can also be used as a spectral filter using the hole burning techniques. [60] In 2015, Riedmatten's group used a second memory crystal as a filter and successfully stored the time-bin qubits with the full AFC protocol in a Pr 3+ :Y 2 SiO 5 crystal, which has an SNR over 10 for the signal at SPL. [61] The efficiency of spin-wave storage was also improved in recent years.…”

The reversible transfer of unknown quantum states between light and matter is essential for constructing large-scale quantum networks. Over the last decade, various physical systems have been proposed to realize such quantum memory for light. The solid-state quantum memory based on rare-earth-ion-doped solids has the advantages of a reduced setup complexity and high robustness for scalable application. We describe the methods used to spectrally prepare the quantum memory and release the photonic excitation on-demand. We will review the state of the art experiments and discuss the perspective applications of this particular system in both quantum information science and fundamental tests of quantum physics.
