Qubit Chip / Device
Host the superconducting qubit(s). The final endpoint for all quantum control and readout wiring.
What it does
The superconducting qubit device package. Mounted in a copper or aluminium sample holder at the MXC stage. All quantum control and readout topologies must ultimately terminate here. Exposes logical ports for XY drive, readout resonator (in/out), flux bias, and optional DC bias.
