Inducing micromechanical motion by optical excitation of a single quantum dot
Jan Kettler, Nitika Vaish, Laure Mercier de Lépinay +11
Hybrid quantum optomechanical systems offer an interface between a single two-level system and a macroscopical mechanical degree of freedom. In this work, we build a hybrid system…
Two-photon interference in the telecom C-band after frequency conversion of photons from remote quantum emitters
Jonas H. Weber, Benjamin Kambs, Jan Kettler +7
Efficient fiber-based long-distance quantum communication via quantum repeaters relies on deterministic single-photon sources at telecom wavelengths, with the potential to exploit…
Overcoming correlation fluctuations in two-photon interference experiments with differently bright and independently blinking remote quantum emitters
Jonas H. Weber, Jan Kettler, Hüseyin Vural +5
As a fundamental building block for quantum computation and communication protocols, the correct verification of the two-photon interference (TPI) contrast between two independent…
Tuning emission energy and fine structure splitting in quantum dots emitting in the telecom O-band
Bianca Höfer, Fabian Olbrich, Jan Kettler +7
We report on optical investigations of MOVPE-grown InGaAs/GaAs quantum dots emitting at the telecom O-band that were integrated onto uniaxial piezoelectric actuators. This promisin…
