    Propagation losses have limited the practical use of polaritons in photonic applications. Here the authors demonstrate a substantial enhancement in the propagation distance of phonon polaritons, employing synthetic optical excitation of complex frequency with virtual gain synthesized by combining multiple real frequency measurements.
