We discuss achieving attosecond-level temporal resolution via Hong-Ou-Mandel interferometry using highly non-degenerate frequency-entangled photons. This approach offers robustness against dispersion and loss, and facilitates novel sensing schemes in regimes inaccessible by existing interferometers.
