Extending the coherence time of spin defects in hBN enables advanced qubit control and quantum sensing
Roberto Rizzato, Martin Schalk, Stephan Mohr +10
Spin defects in hexagonal Boron Nitride (hBN) attract increasing interest for quantum technology since they represent optically-addressable qubits in a van der Waals material. In p…
Coherent Dynamics of the Swing-Up Excitation Technique
Katarina Boos, Friedrich Sbresny, Sang Kyu Kim +9
Developing coherent excitation methods for quantum emitters which enable high brightness, good single-photon purity and high indistinguishability of the emitted photons has been a…
The quantum dynamic range of room temperature spin imaging
Martin Schalk, Riccardo Silvioli, Karina Houska +8
Magnetic resonance imaging of spin systems combines scientific applications in medicine, chemistry and physics. Here, we investigate the pixel-wise coherent quantum dynamics of spi…
Two-Photon Interference of Single Photons from Dissimilar Sources
Christian Dangel, Jonas Schmitt, Anthony J. Bennett +2
Entanglement swapping and heralding are at the heart of many protocols for distributed quantum information. For photons, this typically involves Bell state measurements based on tw…
Three-photon excitation of quantum two-level systems
Viviana Villafañe, Bianca Scaparra, Manuel Rieger +8
We demonstrate that semiconductor quantum dots can be excited efficiently in a resonant three-photon process, whilst resonant two-photon excitation is highly suppressed. Time-depen…
