Qt3D uses OpenGL so you would normally render to the framebuffer and capture that. There is even a "Qt example":http://doc.qt.nokia.com/latest/opengl-grabber.html that shows how to do this.

To improve quality you need to render the scene with "better" settings - be they shaders, multisampling buffers, multiple passes etc. That is up to you to do though and it depends what you man by "high quality".
