Spectral multiplexing of telecom emitters with stable transition frequency
Alexander Ulanowski, Benjamin Merkel, Andreas Reiserer
In a quantum network, coherent emitters can be entangled over large distances using photonic channels. In solid-state devices, the required efficient light-emitter interface can be…
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…
Dynamical decoupling of spin ensembles with strong anisotropic interactions
Benjamin Merkel, Pablo Cova Fariña, Andreas Reiserer
Ensembles of dopants have widespread applications in quantum technology. The miniaturization of corresponding devices is however hampered by dipolar interactions that reduce the co…
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…
A charge-driven feedback loop in the resonance fluorescence of a single quantum dot
B. Merkel, A. Kurzmann, J. -H. Schulze +3
Semiconductor quantum dots can emit antibunched, single photons on demand with narrow linewidths. However, the observed linewidths are broader than lifetime measurements predict, d…
Optical blocking of electron tunneling into a single self-assembled quantum dot
A. Kurzmann, B. Merkel, P. A. Labud +4
Time-resolved resonance fluorescence (RF) is used to analyse electron tunneling between a single self-assembled quantum dot (QD) and an electron reservoir. In equilibrium, the RF i…
First Results from the Cryogenic Dark Matter Search in the Soudan Underground Lab
CDMS Collaboration
We report the first results from a search for weakly interacting massive particles (WIMPs) in the Cryogenic Dark Matter Search (CDMS) experiment at the Soudan Underground Laborator…
Prototype Tests for the CELESTE Solar Array Gamma--Ray Telescope
B. Giebels, R. Bazer-Bachi, H. Bergeret +24
The CELESTE experiment will be an Atmospheric Cherenkov detector designed to bridge the gap in energy sensitivity between current satellite and ground-based gamma-ray telescopes, 2…
