Entangled microwave photons generation using cryogenic low noise amplifier (transistor nonlinearity effects)

Abstract This article mainly focuses on important quantum phenomenon called entanglement arising the nonlinearity property. study uses a unique approach in which transistor effect (third-order nonlinearity) entangled microwave photons are created cryogenic low-noise amplifier (LNA). For analysis, Hamiltonian of designed LNA (containing two coupled oscillators) is derived, and then, using dynamic equation motion, oscillator’s number phase-sensitive cross-correlation factor calculated Fourier domain to calculate metric. The oscillators each other through gate–drain capacitor, nonlinear transconductance as an strongly manipulating entanglement. As main conclusion, shows that circuit third-order has ability generate at very low intrinsic more importantly when noise figure (NF) minimized. complementary task, printed board simulated verify achieve ultralow NF, by probability generation increased.
