The recent developments of optoelectronics do promote the progress in many other fields. For quantum information processing, we made efforts in manufacturing quantum devices by using optoelectronic techniques. We designed quantum dot embedded nanocavities to serve as efficient quantum emitters; using spectral multiplexing technique, we fabricated a heralded single-photon source, emitting highly pure and speedy single photons; and defects in GaN were observed serving as room temperature quantum random number generators. An entangled photon emitter with visibility of 97% was developed using cascaded second-order nonlinear optical process in PPLN waveguides; and Si3N4 microrings were effectively applied to establish photon entanglers. Readout circuits were optimized to fabricate specific single-photon avalanche detectors, and telecomm-band single-photon avalanche detectors have been improved to 128 × 32 arrays for quantum imaging. A multiplexed quantum memory was explored to simultaneously store 1650 single photons. Opto-electro-mechanical devices were studied or fabricated in order to measure minor quantities in quantum level. These works may shed light on quantum information technology for the future.

“…Denoted as photon-assisted entanglement [25], this mechanism is found in different microscopic physical [26] and biological [27] systems, and is responsible for emergent behavior on macroscopic scales. Following this approach, it is expected to detect such synchronization effects in electrochemical systems that are observed in coupled quantum oscillators [30], [31], spin ensembles under light excitation [29] or optomicromechanics [28]. Since spin-level phenomena are involved into macroscopic synchronization, investigation of these quantum mechanisms can be conducted with low-cost EIS or mobile NMR [32], [33] sensors, which can lead to new quantum sensing technologies.…”

We theoretically study the optical second-order sideband (OSS) generation in a hybrid cavity optomechanical system, which consists of an optomechanical cavity trapping a nitrogen-vacancy (NV) spin ensemble and an auxiliary cavity. Compared with ordinary optomechanical system, the results show that the OSS generation is more obvious in both red probe-pump resonant detuning case and blue one when NV spin ensemble is coupled to the optomechanical cavity. Besides, the significant improvement of OSS efficiency can be realized by tuning the collective spin-cavity coupling and the spin-pump detuning. By optimizing the collective spin-cavity coupling strength and the spin-pump detuning together, the efficiency of OSS can be higher than that of first-order sideband. Moreover, we demonstrate that the OSS efficiency can be modulated effectively by the decay rate of NV spin ensemble. Meantime, it is proved that the tunnelling strength between the optomechanical cavity and auxiliary cavity also plays a dispensable role on the OSS generation. Interestingly, in the red probe-pump resonant case, the OSS efficiency undergoes a process of first deceasing and then increasing as the tunnelling strength increases. These results provide some guidance for enhancing OSS efficiency and controlling light propagation, which facilitates the practicable applications in optical communication and storage.
