| Popis: | This study unveils a groundbreaking exploration of using semiconductor technology in quantum circuitry. Leveraging the unique operability of 45 nm CMOS technology at deep cryogenic temperatures (~ 300 mK), a novel quantum electronic circuit is meticulously designed. Through the intricate coupling of two matching circuits via a 45 nm nMOS transistor, operating as an open quantum system, the circuit quantum Hamiltonian and the related Heisenberg-Langevin equation are derived, setting the stage for a comprehensive quantum analysis. Central to this investigation are three pivotal coefficients derived, which are the coupling between the coupled oscillator charge and flux operators through the internal circuit of the transistor. These coefficients emerge as critical determinants, shaping both the circuit potential as a parametric amplifier and its impact on quantum properties. The study unfolds a delicate interplay between these coefficients, showcasing their profound influence on quantum discord and the gain of the parametric amplifier. Consequently, the assimilation of 45 nm CMOS technology with quantum circuitry makes it possible to potentially bridge the technological gap in quantum computing applications, where the parametric amplifier is a necessary and critical device. The designed novel quantum device serves not only as a quantum parametric amplifier to amplify quantum signals but also enhances the inherent quantum properties of the signals such as non-classicality. Therefore, one can create an effective parametric amplifier that simultaneously improves the quantum characteristics of the signals. The more interesting result is that if such a theory becomes applicable, the circuit implemented in the deep-cryogenic temperature can be easily compatible with the next step of circuitry while keeping the same electronic features compatibility with the quantum processor.
