Quantum Computer Architecture

A proposed Von Neumann architecture for a quantum computer  

In this image, quantum information (blue and red cubes representing 0 and 1 bits of information) is processed in the top layer of the architecture (disordered cubes), the quantum CPU. The information then funnels to the second layer, where it is stored in the quantum memory (ordered cubes), the quantum RAM. Unnecessary quantum information that has already been utilized can finally be deleted on the bottom layer (cubes fading away), the zeroing register.
