“…Nonreciprocal photon blockade may have important applications in the development of quantum nonreciprocal devices, which are crucial elements in chiral quantum technologies or topological photonics. Different from the nonreciprocity induced by nonlinearity, the nonreciprocal transmission based on synthetic magnetism can work for weak signals and has been widely studied in a variety of systems, such as microwave resonators connected with Josephson junctions [28][29][30][31], optomechanical systems with parametric coupling between optical and mechanical modes [32][33][34][35][36][37][38][39][40][41]. However, nonreciprocal photon blockade has not been considered in the systems with synthetic magnetism yet.…”

We propose how to realize nonreciprocity for a weak input optical field via nonlinearity and synthetic magnetism. We show that the photons transmitting from a linear cavity to a nonlinear cavity (i.e., an asymmetric nonlinear optical molecule) exhibit nonreciprocal photon blockade but no clear nonreciprocal transmission. Both nonreciprocal transmission and nonreciprocal photon blockade can be observed, when one or two auxiliary modes are coupled to the asymmetric nonlinear optical molecule to generate an artificial magnetic field. Similar method can be used to create and manipulate nonreciprocal transmission and nonreciprocal photon blockade for photons bi-directionally transport in a symmetric nonlinear optical molecule. Additionally, a photon circulator with nonreciprocal photon blockade is designed based on nonlinearity and synthetic magnetism. The combination of nonlinearity and synthetic magnetism provides us an effective way towards the realization of quantum nonreciprocal devices, e.g., nonreciprocal single-photon sources and single-photon diodes.

“…In general, nonreciprocity can be realized by tuning the relative phase between different interference paths. With this method, optical isolators [28][29][30][31][32][33], circulators [29,34,35], and directional amplifiers [36][37][38][39] have been theoretically studied and experimentally realized. Inspired by the Sagnac effect, however, nonreciprocal optical transmissions can also be realized by spinning a whispering-gallery-mode (WGM) resonator [40,41].…”

We study the quantum interference between different weak signals in a three-port optomechanical system, which is achieved by coupling three cavity modes to the same mechanical mode. If one cavity serves as a control port and is perturbed continually by a control signal, nonreciprocal quantum interference can be observed when another signal is injected upon different target ports. In particular, we exhibit frequency-independent perfect blockade induced by the completely destructive interference over the full frequency domain. Moreover, coherent photon routing can be realized by perturbing all ports simultaneously, with which the synthetic signal only outputs from the desired port. We also reveal that the routing scheme can be extended to more-port optomechanical systems. The results in this paper may have potential applications for controlling light transport and quantum information processing.

“…[26][27][28][29] On the other hand, COM-based optical nonreciprocal phenomena have also attracted significant interest in the decades, which means that the transmission of signals in two opposite directions exhibits different characteristics. Optical nonreciprocity has been realized in various optomechanical structures, [30][31][32] such as magneto-optical crystals, [33][34][35] optical nonlinear systems, [36][37][38] spatial-symmetry-breaking structures, [39][40][41] and parity-time-symmetric structures. [42][43][44] Nonreciprocal devices based on nonreciprocity, for example, isolator, directional amplifier, circulator, and so on, play significantly important roles in quantum information processing and communication.…”

Summary We propose a scheme to realize optical nonreciprocal response and conversion in a Tavis‐Cummings coupling optomechanical system, where a single cavity mode interacts with the vibrational mode of a flexible membrane with an embedded ensemble of two‐level quantum emitters. Due to the introduction of the Tavis‐Cummings interaction, we find that the phases between the mechanical mode and the optical mode, as well as between the mechanical mode and the dopant mode, are correlated with each other, and further give the analytical relationship between them. By optimizing the system parameters, especially the relative phase between two paths, the optimal nonreciprocal response can be achieved. Under the frequency domain, we derive the transmission matrix of the system analytically based on the input‐output relation and study the influence of the system parameters on the nonreciprocal response of the quantum input signal. Moreover, compared with the conventional optomechanical systems, the Tavis‐Cummings coupling optomechanical system exhibits richer nonreciprocal conversion phenomena among the optical mode, mechanical mode, and dopant mode, which provide a new applicable way of achieving the phonon‐photon transducer and the optomechanical circulator in future practice.
