DESCRIPTION
The development of quantum computing systems relies on the ability to rapidly and precisely measure these systems' electrical properties, such as their underlying charge and spin states. These measurements are typically collected using radio-frequency resonators, which are tuned using voltage-controlled capacitors known as varactors.
