Autor: Mohammad T. Amawi, Andrii Trelin, You Huang, Paul Weinbrenner, Francesco Poggiali, Joachim Leibold, Martin Schalk, Friedemann Reinhard

Publikováno v: npj Quantum Information, Vol 10, Iss 1, Pp 1-6 (2024)

Abstract We demonstrate three-dimensional magnetic resonance tomography with a resolution down to 5.9 ± 0.1 nm. Our measurements use lithographically fabricated microwires as a source of three-dimensional magnetic field gradients, which we use to im

Abstract Negatively-charged boron vacancy centers ( $${{V}_{B}}^{-}$$ V B − ) in hexagonal Boron Nitride (hBN) are attracting increasing interest since they represent optically-addressable qubits in a van der Waals material. In particular, these sp

Publikováno v: Nature Communications, Vol 9, Iss 1, Pp 1-6 (2018)

Electronic excitations in low-dimensional quantum nanoelectronic devices are collective waves that are strongly affected by the Coulomb interaction. Here, the authors demonstrate that they are able to prepare these collective excitations down to the

Unveiling the Zero-Phonon Line of the Boron Vacancy Center by Cavity Enhanced Emission

Autor: Chenjiang Qian, Viviana Villafañe, Martin Schalk, G. V. Astakhov, Ulrich Kentsch, Manfred Helm, Pedro Soubelet, Nathan P. Wilson, Roberto Rizzato, Stephan Mohr, Alexander W. Holleitner, Dominik B. Bucher, Andreas V. Stier, Jonathan J. Finley

Negatively charged boron vacancies ($V_B^-$) in hexagonal boron nitride (hBN) exhibit a broad emission spectrum due to strong electron-phonon coupling and Jahn-Teller mixing of electronic states. As such, the direct measurement of zero-phonon line (Z
