We run a selection of algorithms on two state-of-the-art 5-qubit quantum computers that are based different technology platforms. One is publicly accessible superconducting transmon device with limited connectivity, and the other fully connected trapped-ion system. Even though systems have native interactions, both can be programmed in way blind to underlying hardware, thus allowing first comparison identical between physical systems. show circuits employ more connectivity clearly benefit from better system qubits. While here not yet large enough eclipse classical computers, this experiment exposes critical factors scaling such as qubit gate expressivity. In addition, results suggest co-designing particular applications hardware itself will paramount successfully using future.
