Conductance and microwave/RF spectroscopy underpins state readout for leading solid-state quantum computing platforms. P2 is a highly customisable system for characterising time-domain coherence in quantum devices 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.
