Intended to help quantum computation students explore and play with a number of different quantum computer gates.
The blue discs represent basis state amplitudes: for a given amplitude, the radius is its magnitude and arrow direction is its phase. When performing operations like the Hadamard and QFT operations, the discs are animated in a manner that shows states being split and recombined (arrow head joined to arrow tail), demonstrating constructive and destructive interference.
