Engineering Long-Lived Vibrational States for an Organic Molecule

The optomechanical character of molecules was discovered by Raman about one century ago. Today, are promising contenders for high-performance quantum platforms because their small size and large energy-level separations make them intrinsically robust against thermal agitations. Moreover, the precision throughput chemical synthesis can ensure a viable route to technological applications. challenge, however, is that coupling molecular vibrations environmental phonons limits coherence picosecond time scales. Here, we improve quality molecule several orders magnitude through phononic engineering its surrounding. By dressing with long-lived high-frequency phonon modes nanoscopic environment, achieve storage retrieval photons at millisecond timescales allow emergence single-photon strong in optomechanics. Our strategy be extended realization networks.
