Quantum light gets a place to wait with new on-chip memory

Researchers at the University of Illinois Urbana-Champaign have developed an integrated nanophotonic platform that can store multiple photons simultaneously for over one microsecond. The chip-based quantum memory uses erbium-doped thin-film lithium niobate waveguides arranged in an atomic frequency comb pattern to capture and hold photons.
