Control signals operate directly on the fragile quantum states, that is, on the most sensitive elements of a quantum processor. Zurich Instruments' signal generation products combine our expertise in analog circuit design with our in-depth knowledge of the requirements related to different implementations of superconducting and spin qubit gates. Performance in terms of 1/f noise, phase noise, bandwidth, and amplitude stability is carefully balanced whether the quantum device in use features on flux bias, charge bias, parametric, or cross-resonance gates.
