High-rate single photons in a pure quantum state for quantum communication
Christoph Kurz, Jan Huwer, Michael Schug, Philipp Müller, Jürgen Eschner · 2013
We generate high-rate single photons in a single quantum state by spontaneous Raman scattering in a trapped ion. Photon frequency, polarization and temporal shape are laser-controlled. The photons create quantum jumps in another, distant ion.
