Doppler-free three-photon coherence effects in mercury vapor
Benjamin Rein, Jochen Schmitt, Martin R. Sturm +2
Doppler-free three-photon coherence effects at a wavelength of 253.7 nm have been observed in thermal mercury vapor. The experimental results are compared to simulations based on a…
Time-dependent POVM reconstruction for single-photon avalanche photo diodes using adaptive regularization
E. Fitzke, R. Krebs, Th. Haase +3
We report on the first realization of time-dependent quantum detector tomography for commercially available InGaAs avalanche photo detectors. For the construction of appropriate ti…
A scalable network for simultaneous pairwise quantum key distribution via entanglement-based time-bin coding
Erik Fitzke, Lucas Bialowons, Till Dolejsky +5
We present a scalable star-shaped quantum key distribution (QKD) optical fiber network. We use wavelength-division demultiplexing (WDM) of broadband photon pairs to establish key e…
Feasibility of UV lasing without inversion in mercury vapor
Martin R. Sturm, Benjamin Rein, Thomas Walther +1
We investigate the feasibility of UV lasing without inversion at a wavelength of nm utilizing interacting dark resonances in mercury vapor. Our theoretical analysis starts…
