Coherent Control and Wave Mixing in an Ensemble of Silicon-Vacancy Centers in Diamond

Abstract

Strong light-matter interactions are critical for quantum technologies based on light, such as memories or nonlinear interactions. Solid state materials will be particularly important for such applications, because of the relative ease of fabrication of components. Silicon vacancy centers (SiV − ) in diamond feature especially narrow inhomogeneous spectral lines, which are rare in solid materials. Here, we demonstrate resonant coherent manipulation, stimulated Raman adiabatic passage, and strong light-matter interaction via four-wave mixing of a weak signal field in an ensemble of SiV − centers.

Multidimensional four-wave-mixing spectroscopy with squeezed light

“…The simulated photoluminescence spectrum shown in Fig. 2(a) agrees with experiment, 22 and has four features. 23,24 Figure 2(b) shows the Gain spectrum given by Eq.…”

Building Blocks for Quantum Network Based on Group‐IV Split‐Vacancy Centers in Diamond

“…As for the second scenario of three‐level Λ‐system involving two orbital ground states, the coherent control has also been illustrated on either a single SiV − center or an ensemble by employing STIRAP scheme. The ensemble shows a coherence time of in agreement with coherent population transfer measurement .…”

Spectroscopic investigations of negatively charged tin-vacancy centres in diamond

“…At the same time, it is necessary to maintain scalability of such devices which is an advantage inherent to solid state emitters. Among potential candidates [1,2], colour centres in diamond were shown to be highly suitable to encounter many of the tasks set in QIP such as coherent manipulation of single spins with long coherence times [3][4][5][6], single photon nonlinearities [7], strong light-matter interactions [8] and entanglement of remote spins [9,10]. More specifically, two colour centres raised strong interest, i.e.…”
