In our most recent manuscript, published in Applied Physics Letter, we present an improved method for the creation of narrow-linewidth nitrogen-vacancy centers (NVs) in microstructured diamond. NVs are known for their exceptional spin coherence and convenience in optical spin initialization and readout, and are increasingly used both as a quantum sensor and as a building

Natasha Tomm has received two awards for her PhD thesis “A quantum dot in a microcavity as a bright source of coherent single photons” this year! The first prize was the Prix Schläfli in Physics 2022, awarded by the Swiss Academy of Sciences (SCNAT). The Prix Schläfli is one of the oldest prizes in Switzerland and

In our recent publication in Physical Review Letters, we experimentally and theoretically study exciton-exciton couplings in a two-dimensional semiconductor, homobilayer MoS2. More information can be found in the SNI news or in this short explanation video.

Simon Geyer was recognized with the Swiss Nanotechnology PhD award sponsored by the IBM Research Zürich for the publication “A hole spin qubit in a fin field-effect transistor above 4 kelvin”. Congratulations!!  

Recently published in Nature Nanotechnology, we demonstrate quantum interference between single photons from separate quantum dots. Such a demonstration has been attempted multiple times in the past decade and appeared challenging. The problem is the noise: the noise affects the photon creation process of different quantum dots in different ways. Thus, single photons created by

In our recent publication in npj Quantum Information we have demonstrated a chiral one-dimensional atom using a single semiconductor quantum dot in a tunable microcavity. In a chiral atom, photons propagating in one direction interact with the atom, while photons propagating in the other direction do not. Here, we achieve strong non-reciprocal absorption of single-photons,
