J. R. Johansson, G. Johansson, C. M. Wilson and Franco Nori study the dynamical Casimir effect in a superconducting coplanar waveguide ended by a SQUID. Vacuum fluctuations pull two parallel mirrors together, and a moving mirror can turn them into real photons. Changing the magnetic flux through the SQUID modulates the waveguide's boundary condition and so its effective length, acting like a moving mirror. Effective boundary speeds near the speed of light in the waveguide produce broadband photons identical to those predicted for a single oscillating mirror. Estimating the power for realistic parameters, they show this nonclassical radiation should be directly detectable in experiments.
