• Abstract: A challenging task of cavity optomechanics is to observe single-photon optomechanical effects. To explore an intrinsic nonlinear effect of single-photon cavity optomechanics, we need to strengthen the radiation-pressure (RP) interaction between a single photon and a finite number of phonons. In this work, introducing the two-laser driving and considering the second-order correction to the cavity resonance frequency beyond the RP interaction, we realize controllable enhancement of the single-photon optomechanical coupling in a prototypical Fabry-Perot cavity. By adjusting the parameters of the two driving lasers and the cross-Kerr (CK) interaction so that the effective optomechanical coupling may become a real number, we theoretically propose effective symmetric optomechanical dynamics at the single-photon level, in which the forms of the quantum fluctuation dynamics satisfied by the photon and phonon are identical to each other. We study optimal reciprocal transport in symmetric optomechanics. By observing the critical behavior of the optimal transmission of the laser field, we identify the boundary point of the optomechanical strong coupling. We compare the scattering behavior of the laser field in the dissipative equilibrium and non-equilibrium symmetric optomechanics before and after the rotating-wave approximation (RWA). We also present a reliable experimental implementation of the present scheme. This work may pave the way to studying the single-photon optomechanical effects with current experimental platforms.

  Two non-identical quantum emitters, when placed within a cavity and coherently excited at the two-photon resonance, can reach stationary states of nearly maximal entanglement. We show that this mechanism is merely one among a complex family of phenomena that can generate both stationary and metastable entanglement when driving the emitters at the two-photon resonance.

  Adding or subtracting a single quantum of excitation to a thermal state of a bosonic system has the counter-intuitive effect of approximately doubling its mean occupation. We perform the first experimental demonstration of this effect outside optics by implementing single-phonon addition and subtraction. We observe this doubling of the mechanical thermal fluctuations to a high precision using a detection scheme that combines single-photon counting and optical heterodyne detection.
