Quantum Inspire Tuna-17
Quantum Inspire Tuna-17 is a superconducting circuits quantum computer operated by QuTech in Netherlands. It has 17 physical qubits. It ranks 58 of 74 superconducting machines in this table by physical qubit count. 7 sourced specs are in the spec sheet. No benchmark figures are recorded for it yet.
Also known as Tuna-17
Largest Tuna processor on the Quantum Inspire cloud, available since April 2026 according to the Quantum Inspire backends page. Like Tuna-9 (quantum-inspire-tuna-9) it sits on sapphire with three readout feedlines and room-temperature Qblox control. The page gives no fidelity, coherence or gate-time numbers, so the entry carries structure and availability only.
