Tailoring photonic entanglement in high-dimensional Hilbert spaces
Tailoring photonic entanglement in high-dimensional Hilbert spaces
We present an experiment where two photonic systems of arbitrary dimensions can be entangled. The method is based on spontaneous parametric down conversion with trains of d pump pulses with a fixed phase relation, generated by a mode-locked laser. This leads to a photon pair created in a coherent superposition …
