  In this study, we introduce an online public quantum computation platform,
named as ScQ, based on a 1D array of a 10-qubit superconducting processor.
Single-qubit rotation gates can be performed on each qubit. Controlled-NOT
gates between nearest-neighbor sites on the 1D array of 10 qubits are
available. We show the online preparation and verification of
Greenberger-Horne-Zeilinger states of up to 10 qubits through this platform for
all possible blocks of qubits in the chain. The graphical user interface and
quantum assembly language methods are presented to achieve the above tasks,
which rely on a parameter scanning feature implemented on ScQ. The performance
of this quantum computation platform, such as fidelities of logic gates and
details of the superconducting device, are presented.
