Coherent control in the ground and optically excited state of an ensemble of erbium dopants
Pablo Cova Fariña, Benjamin Merkel, Natalia Herrera Valencia +3
Ensembles of erbium dopants can realize quantum memories and frequency converters that operate in the minimal-loss wavelength band of fiber optical communication. Their operation r…
Laser stabilization to a cryogenic fiber ring resonator
Benjamin Merkel, Daniel Repp, Andreas Reiserer
The frequency stability of lasers is limited by thermal noise in state-of-the-art frequency references. Further improvement requires operation at cryogenic temperature. In this con…
Coherent and Purcell-enhanced emission from erbium dopants in a cryogenic high-Q resonator
Benjamin Merkel, Alexander Ulanowski, Andreas Reiserer
The stability and outstanding coherence of dopants and other atom-like defects in tailored host crystals make them a leading platform for the implementation of distributed quantum…
Erbium dopants in silicon nanophotonic waveguides
Lorenz Weiss, Andreas Gritsch, Benjamin Merkel +1
The combination of established nanofabrication with attractive material properties makes silicon a promising material for quantum technologies, where implanted dopants serve as qub…
Magnetic field stabilization system for atomic physics experiments
B. Merkel, K. Thirumalai, J. E. Tarlton +4
Atomic physics experiments commonly use millitesla-scale magnetic fields to provide a quantization axis. As atomic transition frequencies depend on the amplitude of this field, man…
Photon noise suppression by a built-in feedback loop
A. Al-Ashouri, A. Kurzmann, B. Merkel +4
Visionary quantum photonic networks need transform-limited single photons on demand. Resonance fluorescence on a quantum dot provides the access to a solid-state single photon sour…
