A D-band $\times$ 8 frequency multiplier is presented in this letter. The $\times$ 8 frequency multiplier consists of two stages of the newly proposed common load complementary push-push doublers (CL-CPPDs) and one stage of NMOS push-push doubler. The proposed CL-CPPD uses a single load to generate a balanced output with high harmonic rejection (HR) and can be easily cascaded using transformers for a high multiplication ratio with low dc power consumption. The chip is fabricated by using a 40-nm CMOS technology, and it achieves a maximum output power of $-$ 2.48 dBm with an input power of $0$ dBm in the frequency range of 131.2–144.8 GHz. All HRs are over 34 dBc in the frequency range of 131.2–144.8 GHz. The total dc power dissipation is 41.4 mW when supplied from a single voltage of 0.9 V and occupies 0.37 ${\mathrm{mm}}^{2}$ of the chip area. IEEE

Strong quantum correlated sources are essential but delicate resources for quantum information science and engineering protocols. Decoherence and loss are the two main disruptive processes that lead to the loss of nonclassical behavior in quantum correlations. In quantum systems, scattering can contribute to both decoherence and loss. In this work, we present an experimental scheme capable of significantly mitigating the adverse impact of scattering in quantum systems. Our quantum system is composed of a two-mode squeezed light generated with the four-wave-mixing process in hot rubidium vapor and a scatterer is introduced to one of the two modes. An integrating sphere is then placed after the scatterer to recollect the scattered photons. We use mutual information between the two modes as the measure of quantum correlations and demonstrate a 47.5% mutual information recovery from scattering, despite an enormous photon loss of greater than 85%. Our scheme is the very first step toward recovering quantum correlations from disruptive random processes and thus has the potential to bridge the gap between proof-of-principle demonstrations and practical real-world implementations of quantum protocols.
