“…One is by adding an auxiliary cavity between two cavity modes [24], and the other is to add an auxiliary driving field so that the cavity and atoms are simultaneously driven [6]. Based on this feature, many schemes have been proposed to implement UPB, such as two coupled single-mode cavities with nonlinearity [24][25][26][27], cavity embedded with a quantum dot [28][29][30], degenerate optical parametric amplifier system [31][32][33], and two coupled superconducting resonators system [34][35][36][37].…”

Simultaneously enhanced photon blockades in two microwave cavities via driving a giant atom

We propose a scheme to enhance photon blockades simultaneously in two microwave cavities connected by a giant atom. In the case that only one cavity is weakly driven, we observe that the enhanced photon blockades occur in both cavities at the same time, which is attributed to the anharmonic eigenenergy spectrum constructed by the resonantly coupled giant atom. When the cavity and the atom are simultaneously driven, the stronger photon blockades in two cavities can be successfully achieved by the destructive quantum interference of two-photon excitation. Interestingly, we find that high single-photon occupations can be obtained in both cases. Moreover, we give the optimal conditions for conventional and unconventional photon blockades through analytical calculations, which are in good agreement with numerical results. Our scheme opens a prospective path to achieve simultaneous photon blockades in two indirectly coupled cavities, and provides a promising method to generate the high-quality and brightness single photon source.

“…The hybrid systems considering interactions between cavities, atoms and mechanical resonators, nowadays are of great importance for many applications in quantum technologies [21][22][23] as well are the promising candidates to probe the foundations of the quantum mechanics, e.g. macroscopic quantum superpositions [24][25][26][27], quantum correlations at macroscopic scales [28,29], phonon and photon blockade effects [30][31][32][33][34][35][36][37][38][39][40].…”

“…Another quantum effect which attracted our interest is the phonon blockade (antibunching). The effects of phonon and photon blockade were intensively studied the last decade, particularly in the hybrid setups [30][31][32][33][34][35][36][37][38][39][40]. In order to realize such an effect commonly one needs a quantum strong nonlineariry in the system, i.e.…”

In a hybrid micromaser system consisting of an optical cavity with a moving mirror connected to a low temperature thermal bath, we demonstrate, both analytically and numerically, that for certain interaction times between a random atomic flux and the optomechanical cavity, vacuum phonon trapping states are generated. Furthermore, under the approach of the master equation with independent phonon and photon thermal baths, we show that the trapping of the phonons and photons is achieved for the same interaction times. The results also indicate that by increasing the cavity-oscillator coupling one may generate a coherent phonon state aside from the trapping states. Within the same hybrid system, but now connected to the squeezed phonon reservoir, a phonon blockade effect can be engineered. Moreover, we identify an interconnection between the trapping and blockade effects, particularly if one approaches the vacuum trapping state, strong phonon blockade can be achieved when the system is connected with a weakly squeezed phonon reservoir.

“…Furthermore, one can tune the frequencies of double OMIT by changing the parameters related to the TLS. Double EIT can be used for double-channel optical communication [ 16 ], tunable cross-phase modulation [ 17 ], high-speed optical switches [ 18 ], phonon heat transport controller [ 19 ] and a single phonon generator [ 20 , 21 , 22 ].…”

With the presence of a driving field applied to double quantum dots and a control field applied on the cavity, the transmission performance and group delay effect of a probe field have been theoretically studied in a hybrid optomechanical system (HOMS). Due to the interaction between the mechanical mode and the double quantum dots system, double optomechanically induced transparency (OMIT) arises in the HOMS. With the assistance of a driving field, the system can be tuned to switch on any one of the two OMIT windows, switch on both of the two OMIT windows or switch off both of the two OMIT windows by dynamically adjusting control of the optical field and the driving field. Furthermore, the transmitted probe fields of the two OMIT windows can be tuned to be absorbed or amplified with proper parameters of the driving field and control field. Moreover, the transmission properties of the two OMIT windows are asymmetrical. One can obtain the maximum group delay time of the probe field by optimizing the amplitude and phase of the driving field. These results provide a new way for constructing optically controlled nanostructured photonic switch and storage devices.
