“…The error probability is obtained in two parts corresponding to the absence or presence of the target (the false-alarm probability f P and the miss probability r P ). The error probability in quantum receivers is [15,[34][35][36][37][38][39][40][41][42][43][44][45]:…”

“…This figure shows that when the correlation increases, the SNR of the QTMS radar also increases. Therefore, the correlation and entanglement play the most important role in QTMS radars and we need to fabricate more correlated signal and idler (by engineering the JPAs) [37][38][39][40][41][42][43][44][45]. In this model, the qualitative behavior of the correlation function shows that increasing the bandwidth does not suppress the correlation, as is shown in Fig.…”

Josephson parametric amplifier (JPA) engineering is a significant component in the quantum two-mode squeezed radar (QTMS), to enhance, for instance, radar performance and the detection range or bandwidth. In this study, we apply quantum theory to a research domain focusing on the simulation of QTMS radar. We simulate a proposal of using engineered JPA (EJPA) to enhance the performance of a QTMS radar. We define the signal-to-noise ratio (SNR) and detection range equations of the QTMS radar. The engineered JPA leads to a remarkable improvement of the quantum radar performance, i.e. a large enhancement in SNR of about 6 dB more than the conventional QTMS radar (with respect to the latest version of QTMS radar, and not to classical radar), a substantial improvement in the probability of detection through far fewer channels. Finally, we simulate signal transmission to target in QTMS radar and achieve a huge increase in QTMS radar range, from half a meter in the conventional JPA to 482 m in the current study.

“…20 Another choice is to construct specials device structure such as optical microcavity to realize select-wavelength detection [21][22][23] . The resonance microcavity was widely applied in the realization of very narrowband detection due to the resonance enhance absorption effect [24][25][26][27] , which greatly enhance the optical eld in the NIR range through cavity-enhanced charge transfer absorption. However, these types of microcavities were constructed by two re ective silver mirrors and the enhanced resonant NIR absorption is still limited by the photoactive donor and acceptor blend lm.…”

Spectrally selective narrowband Si photodetection is critical for near-infrared (NIR) medical imaging, optical communication, light detection and autonomous mobiles. For conventional inorganic semiconductors such as silicon with broadband absorption from visible until 1.1 µm, it remains challenging to achieve narrowband photodetection without integrating optical filters. We demonstrate the very first narrowest NIR silicon photodetectors without any bandpass filter, reaching the full-width-at-half-maximum of only 26 nm at 912 nm. The narrowband response is inherently attributed to the resonant enhancement effect of optical microcavities formed by patterned Si nanograting combined with the organic D18:Y6 blend film. The Conductive-Atomic Force Microscope (C-AFM), Kelvin Probe Force Microscope (KPFM) and transient absorption (TA) spectroscopy characterization indicate effective charge transfer between Si and organic layers, significantly contributing to ultrafast photoresponse of 74 \(\mu s\). Therefore, this design concept opens up the new possibility of developing filter-less and effective low-cost NIR detection, enabling entirely new configurations of optical imaging devices with narrowband tunability for telecommunications and imaging applications.

“…While using quantum mechanical resonator limits the frequency tunability, the major drawback of this approach is the sensitivity of the mechanical resonator to thermal noise. A different approach is presented in [25]. The entanglement between microwave and optical fields is conducted using an optoelectronic system (compressed of a photodetector and a Varactor diode).…”

We propose a novel approach for microwave and optical fields entanglement using an electrical capacitor loaded with graphene plasmonic waveguide. In the proposed scheme, a quantum microwave signal of frequency ω m drives the electrical capacitor, while an intensive optical field (optical pump) of frequency ω 1 is launched to the graphene waveguide as surface plasmon polariton (i.e., SPP) mode. The two fields interact by the means of electrically modulating the graphene optical conductivity. It then follows that an upper and lower SPP sideband modes (of ω 2 = ω 1 + ω m and ω 3 = ω 1 − ω m frequencies, respectively) are generated. We have shown that the microwave signal and the lower sideband SPP mode are entangled, given a proper optical pump intensity is provided. A quantum mechanics model is developed to describe the fields evolution. The entanglement of the two fields is evaluated versus many parameters including the waveguide length, the pump intensity, and the microwave frequency. We found that the two fields are entangled over a vast microwave frequency range. Furthermore, our calculations show that a significant number of entangled photons are generated at the lower SPP sideband. The proposed scheme attains tunable mechanism for microwave-optical entanglement which paves the way for efficient quantum systems.
