Two Key Advances in Quantum Computing (2 of 8)

Caption

The quantum von Neumann architecture: A classical eye projects and controls a quantum circuit. Quantum information (blue and red little cubes, where the red and blue represents the states 0 and 1 of a quantum bit) is processed in the top layer of the architecture (disordered cubes). The information is then stored in the middle layer, the quantum memory (ordered red and blue cubes). Quantum information that has been already used up can finally be deleted on the bottom layer, where the blue and red cubes are shown to fade away. This image relates to an article that appeared in the Sept. 1, 2011, issue of Science Express, published by AAAS. The study, by Dr. Matteo Mariantoni of University of California, Santa Barbara in Santa Barbara, Calif., and colleagues was titled, "Implementing the Quantum von Neumann Architecture with Superconducting Circuits.”
