Attosecond entangled photons from two-photon decay of metastable atoms: A source for attosecond experiments and beyond
We propose the generation of attosecond entangled biphotons in the extreme-ultraviolet regime by two-photon decay of a metastable atomic state as a source similar to spontaneous parametric down-conversion photons. The 1s2s ^{1}S_{0} metastable state in helium decays to the ground state by the emissi...
