We have recently implemented a machine comprising seven quantum channels\, with three superconducting resonator s\, two phase qubits\, and two zeroing registers.After introducing the m ain concepts on superconducting quantum circuits\, I will explain the de sign and operation of our quantum machine.I will first show how a single microwave photon |1> can be prepared in one resonator and coherently tr ansferred between the three resonators of the machine\, thus allowing us to realize a quantum register on a chip [+].I will then demonstrate how our machine can be used as the quantum-mechanical analog of the von Neu mann computer architecture\, which for a classical computer comprises a central processing unit and a memory holding both instructions and data. The quantum version comprises a quantum central processing unit (quCPU) that exchanges data with a quantum random-access memory (quRAM) integra ted on one chip\, with instructions stored on a classical computer. I wi ll also present a proof-of-concept implementation of a code that involve s all seven quantum elements: (1)\, Preparing an entangled state in the quCPU\, (2)\, writing it to the quRAM\, (3)\, preparing a second state i n the quCPU\, (4)\, zeroing it\, and\, (5)\, reading out the first state stored in the quRAM [*].Finally\, I will demonstrate that the quantum v on Neumann machine provides one unit cell of a two-dimensional qubit-res onator lattice that can be used for surface code quantum computing. This will allow\, (1)\, the realization of a scalable\, fault-tolerant quant um processor with the most forgiving error rates to date and\, (2)\, the possibility to emulate nontrivial many-body systems.
