摘要：Main-stream quantum computers employ dispersive reflectometry for quantum-bit (Qubit) state discrimination. An all-parametric quantum reflectometer (APQR) scheme has been proposed for high-fidelity, scalable Qubit array readout in this letter. For the RF excitation of APQR, a 10.7–16.9 GHz 65-nm cryogenic CMOS (Cryo-CMOS) parametric frequency divider (PFD) is demonstrated here. It adopts a pair of parallelly connected nonlinear artificial transmission lines (NLATLs), a wideband varactor-based dynamic coupler, and a transformer-based CM filter (TCMF). Due to the minimized device self-heating wi
