Building a Quantum Computer
As microelectronics technology nears the end of exponential growth over time, known as Moore’s law, there is a renewed interest in new computing paradigms such as quantum computing. A key step in the roadmap to build a scientifically or commercially useful quantum computer will be to demonstrate its exponentially growing computing power. I will explain how a 7 by 7 array of superconducting qubits can compute over a huge state space of 2^49 = 560 trillion states, which can only be checked using the world’s largest classical supercomputers. We plan to demonstrate this “quantum supremacy” experiment in late 2017.
