We devise and demonstrate a method to search for non-gravitational couplingsof ultralight dark matter to standard model particles using space-timeseparated atomic clocks and cavity-stabilized lasers. By making use ofspace-time separated sensors, which probe different values of an oscillatingdark matter field, we can search for couplings that cancel in typical localexperiments. We demonstrate this method using existing data from a frequencycomparison of lasers stabilized to two optical cavities connected via a 2220 kmfiber link [Nat. Commun. 13, 212 (2022)]. The absence of significantoscillations in the data results in constraints on the coupling of scalar darkmatter to electrons, d_me, for masses between 1e-19 eV and 2e-15 eV. These arethe first constraints on d_me alone in this mass range, and improve the darkmatter constraints on any scalar-Fermion coupling by up to two orders ofmagnitude.
