Conductance and RF/microwave spectroscopy. Leading solid-state quantum computing platforms rely on electrical transport measurements for qubit readout. P2 is a highly customisable system for characterising coherence using DC transport, microwaves (circuit quantum electrodynamics) and RF reflectometry. Typical tests include measuring quality factors of superconducting circuits, critical current-phase relationships of Josephson junctions, and Coulomb blockade and tunnel spectroscopy of quantum dots.
