Need some quantum machine providers

A researcher seeks real quantum hardware providers for a dataset project, requiring superconducting qubits and gate-based systems, excluding simulators. Current access is limited to IBM’s free offerings. The project focuses solely on extracting hardware property data—not algorithm execution—demanding physical quantum machines with specific technical parameters. Superconducting qubits and logic-gate architectures are mandatory, narrowing options to providers like IBM, Rigetti, or Google, though availability remains unclear. Free access is preferred, mirroring IBM’s model, but the researcher invites community suggestions for alternative providers meeting the strict criteria. The request highlights a gap in accessible quantum hardware for academic research, emphasizing the need for expanded open-access options beyond IBM’s ecosystem.
