“…Cavity driven by weak steady beam. Motivated by progress in optomechanics, Rabl [243], Nunnenkamp et al [244] discussed the output photon statistics of such a strongly coupled cavity when weak light is injected. They found the so-called "photon blockade" effect, namely the fact that once a photon is already in the cavity, a second one would not be able to enter very easily because the mirror is oscillating around a new equilibrium point.…”

Abstract. Rapid experimental progress has recently allowed the use of light to prepare macroscopic mechanical objects into nearly pure quantum states. This research field of quantum optomechanics opens new doors toward testing quantum mechanics, and possibly other laws of physics, in new regimes. In the first part of this paper, I will review a set of techniques of quantum measurement theory that are often used to analyze quantum optomechanical systems. Some of these techniques were originally designed to analyze how a classical driving force passes through a quantum system, and can eventually be detected with optimal signal-to-noise ratio -while others focus more on the quantum state evolution of a mechanical object under continuous monitoring. In the second part of this paper, I will review a set of experimental concepts that will demonstrate quantum mechanical behavior of macroscopic objects -quantum entanglement, quantum teleportation, and the quantum Zeno effect. Taking the interplay between gravity and quantum mechanics as an example, I will review a set of speculations on how quantum mechanics can be modified for macroscopic objects, and how these speculations -and their generalizations -might be tested by optomechanics.

“…In this way, the ideal CQED situation, which is also assumed in most proposals on the subject, has been realized [56]: A point-like atom that is trapped at a fixed position within the field of an overcoupled cavity in the strong coupling regime. This is an ideal starting point for the cavity-based generation of nonclassical states of motion [154], the transfer of quantum states between atomic motion and light [155], and the observation of numerous optomechanical effects [19] with single phonons and single photons [156,157]. In addition, the photon emission and absorption efficiencies and fidelities in coherent quantum networks, which we also demonstrated in the course of this thesis [50,51,53], will no longer be limited by the atomic motion.…”

SummaryThis thesis reports on the experimental implementation of a deterministic interaction mechanism between flying optical photons and a single trapped atom. To this end, single rubidium atoms are trapped in a three-dimensional optical lattice at the center of an optical cavity in the strong coupling regime. Full control over the atomic state -its position, its motion, and its electronic state -is achieved with laser beams applied along the resonator and from the side. When faint laser pulses are reflected from the resonator, the combined atom-photon state acquires a state-dependent phase shift. In a first series of experiments, this is employed to nondestructively detect optical photons by measuring the atomic state after the reflection process. In a second series of experiments, quantum bits are encoded in the polarization of the laser pulse and in the Zeeman state of the atom. The state-dependent phase shift then mediates a deterministic universal quantum gate between the atom and one or two successively reflected photons, which is used to generate entangled atom-photon, atom-photon-photon, and photon-photon states out of separable input states.3 4

“…At high pump power, the sideband can be tuned from fast light to slow light, which is potentially useful for optical storage or switch. The enhanced nonlinear OMIT in a Kerr resonator, as revealed here, opens up a promising new way to study other important OM effects, e.g., motion cooling [47] or squeezing [48], lightsound entanglement [49], and photon blockade [50][51][52].As shown in Fig. 1(a), we consider the nonlinear OMIT in a Kerr resonator.…”

We theoretically study high-order optomechanically-induced transparency (OMIT) process in a nonlinear Kerr resonator. A frequency shift induced by the Kerr effect, is identified for the optical cavity mode, which results in asymmetric OMIT windows of the signal and its higher-order sidebands. We also find that both the sideband amplitude and its associated group delay sensitively depend on the strength of the Kerr nonlinearity. This indicates the possibility to enhance or steer the performance of OMIT devices with various nonlinear optical cavities. [5][6][7][8]. A recent advance closely related to the present study is optomechanically induced transparency (OMIT) [9][10][11]. As a solid-state analogy to electromagnetically induced transparency (EIT) originally observed in atomic gases [12], the fundamental OMIT features the two-channel destructive interference of the absorptions of the probe photons (by the cavity itself or the mechanical mode). Beyond this picture, high-order OMIT effects also emerge due to the intrinsic nonlinear OM interactions [13][14][15] [26]. In contrast, high-order OMIT sidebands are generally much weaker than the probe signal and thus hard to be detected or utilized. Hence the sideband enhancement becomes important for its potential applications in e.g., precise sensing of charges [27,28] [42][43][44], and nonlinear OM control [45]. In a recent experiment with a high-Q silica microsphere, asymmetric Fano-like OMIT spectrum was observed due to the optical * Electronic address: jinghui73@gmail.com Kerr effect [46], which can be further tuned or compensated by varying the pump power and the optical frequency.In this paper, based on the OMIT experiment in a Kerr cavity [46], we proceed to study high-order OMIT and its associated group delay in such a nonlinear cavity. We find that in the presence of optical Kerr effect, compared to that in a linear resonator, the amplitude of second-order sideband can be significantly enhanced. This sideband amplitude also can be further tuned by the external light, since the Kerr-induced shift can be either compensated or amplified by varying the pump frequency. Moreover, the delay time of second-order sideband sensitively depends on the Kerr nonlinearity. At high pump power, the sideband can be tuned from fast light to slow light, which is potentially useful for optical storage or switch. The enhanced nonlinear OMIT in a Kerr resonator, as revealed here, opens up a promising new way to study other important OM effects, e.g., motion cooling [47] or squeezing [48], lightsound entanglement [49], and photon blockade [50][51][52].As shown in Fig. 1(a), we consider the nonlinear OMIT in a Kerr resonator. A pump laser of frequency ω l and a probe laser of frequency ω p are applied to the system via the evanescent coupling of the optical fiber and the resonator, the field amplitudes are given bywhere P L and P s are the pump and probe powers, respectively. In the rotating frame at the pump frequency ω l , the Hamiltonian of this OM system is given by (for = 1): ...
