Figure | Experimental schematics and result of the frequency-domain entanglement.

Caption

a, an experimental schematics for the frequency-domain entanglement. Two photons with distinct colors, red and blue, are injected into the interferometer constructed with two frequency beam splitters. Then, the resultant interference pattern is measured. b, The measured interference pattern with the two-photon NOON state, showing a two-fold enhancement in resolution compared to the single-photon counterpart. c, The measured interference pattern with the single-photon state.
