A chip-based quantum memory built from erbium-doped thin-film lithium niobate shows that photons can be held on an integrated nanophotonic platform for more than a microsecond. Using spectral hole burning to form an atomic frequency comb, the device preserves quantum information at high fidelity and stores multiple photons at once. Because the platform supports wafer-scale manufacturing, it points toward practical quantum memories for scalable quantum computers and communicat
