A Flowchart Language for Quantum Programming

From IEEE: A Flowchart Language for Quantum Programming by Feng and Ming. Unfortunately you have to be a member to read it. Selinger did work on a quantum flow chart language back in 2004 [1], so I wonderful how unique this is? I always though visual examples of quantum programming languages portrayed quite a bit, so here's an example of Selinger's "Quantum Flow Charts" or QFC:
