QiB1: Six qubits, three levels of control.
Two sets of qubits — Xmon-style and floating-island — each with a qubit driven through its resonator, one with its own drive line, and one tunable with drive and flux lines. Built for testing control hardware and software.

Shipping and export control
Our quantum devices are EU dual-use items (category 3A001). Every order needs a signed End-User Statement before shipping. Within the EU, and to Australia, Canada, Iceland, Japan, Liechtenstein, New Zealand, Norway, Switzerland, the UK and the US, no individual licence is needed. Anywhere else needs an export licence, which adds time, so tell us your destination early and we'll start the paperwork with you.
