Free-Space distribution of entanglement and single photons over 144 km
R. Ursin, F. Tiefenbacher, T. Schmitt-Manderbach +15
Quantum Entanglement is the essence of quantum physics and inspires fundamental questions about the principles of nature. Moreover it is also the basis for emerging technologies of…
Self-cooling of a micro-mirror by radiation pressure
S. Gigan, H. R. Boehm, M. Paternostro +7
We demonstrate passive feedback cooling of a mechanical resonator based on radiation pressure forces and assisted by photothermal forces in a high-finesse optical cavity. The reson…
A high-reflectivity high-Q micromechanical Bragg-mirror
H. R. Boehm, S. Gigan, G. Langer +6
We report on the fabrication and characterization of a micromechanical oscillator consisting only of a free-standing dielectric Bragg mirror with high optical reflectivity and high…
Experimental interference of independent photons
Rainer Kaltenbaek, Bibiane Blauensteiner, Marek Zukowski +2
Interference of photons emerging from independent sources is essential for modern quantum information processing schemes, above all quantum repeaters and linear-optics quantum comp…
