Quantum computation:  Solid-state qubits under control

D. V. Averin1

One of the most significant developments in physics during the past 20 years is the clear and convincing proof that macroscopic systems, such as a superconductor with billions of electrons in it, can behave quantum mechanically. This conclusion changes the view, which was established in the early days of quantum mechanics, that there is a fundamental difference between the microscopic systems that obey quantum mechanics and the macroscopic world of classical physics.
