WebMay 5, 2024 · Entanglement is a unique quantum information processing feature. With the help of entanglement we can build quantum sensors whose sensitivity is better than that of classical sensors. In this paper we are concerned with the entanglement assisted (EA) bistatic quantum radar applications. By employing the optical phase conjugation (OPC) … WebBy using the property of phase conjugation, we demonstrate that the inverse of van Cittert– Zernike theorem holds for electromagnetic (EM) ﬁelds propagating in free space. This essentially implies that spatially incoherent partially polarized ﬁeld distributions can be generated from spatially coherent partially polarized optical ﬁelds. sharp arrow

WebMay 25, 2024 · An optical setup for generating a phase-conjugate wave from a phase-conjugate mirror by four-wave mixing is shown in Fig. 1. The phase-conjugate mirror is assumed that it responds much faster than the typical fluctuations of chaotic of QD lasers (small value of τ ). WebCoherent population trapping is experimentally identified as the phase-conjugate mechanism. A theoretical model is presented that supports these observations by showing that coherent population trapping can write large-amplitude nonlinear-optical gratings at laser intensities well below those needed to saturate the optical transitions.
