Free tier	"Quantum Computing for everybody - Quick and free registration - Access to our hardware backends - Project storage - Hybrid classical-quantum computing." The hardware is described as "Currently, these are Tuna-5, Tuna-9 and Tuna-17. Tuna-5 has 5 transmons [...] Tuna-9 has 9 transmons [...] Tuna-17 has 17 transmons", alongside a 26-qubit QX emulator and a Rydberg neutral-atom emulator from TU Eindhoven. No card is asked for and no expiry is published. unit minutes; metered on wall-clock; perpetual-open-registration

Composes with	Quantum Inspire is the one provider whose free tier is a physical device rather than a batch queue, so it composes with nothing: the 17-qubit machine cannot be used to prepare data for a GPU job, and the only chain available is the same account also using the emulator for circuit development before spending queue slots on hardware.
Reliability	no reliability event recorded
Notes	A university lab, TU Delft through QuTech, that issues accounts to email addresses with no institutional check and publishes no expiry, which is why this is the cleanest lane fit in the file for the identity question. A third-party comparison table lists QuTech as "free access" that "does not expire", which agrees with the vendor but is not the vendor speaking, so neither sentence is treated as a quota here. Two technical reliability facts from the FAQ matter more than the qubit count: the chips go offline for calibration and upgrades, which the backends page also shows by marking Spin-2+ as taken offline, and the FAQ warns that Chinese providers such as 163.com and qq.com bounce the confirmation mail often enough that users must write to support, which is a practical obstacle for an address on those domains rather than a veto. The free tier's shot allowance per job is not stated on the pages read, so no circuit-throughput figure is given. The corpus holds no Quantum Inspire record.
