Design and Cryogenic Operation of a Hybrid Quantum-CMOS Circuit
Résumé
Silicon-on-insulator nanowire transistors of very small dimensions exhibit electrostatic or quantum effects like Coulomb blockade or single-dopant transport at low temperature. The same process also yields excellent field-effect transistors (FETs) for larger dimensions, allowing us to design integrated circuits. Using the same process, we cointegrate a FET-based ring oscillator circuit operating at cryogenic temperature which generates a radio-frequency (rf) signal on the gate of a nanoscale device showing Coulomb oscillations. We observe rectification of the rf signal, in good agreement with modeling.
