Caption: This is an artist's impression of the creation of an entangled photon pair, a process which is seeded by the vacuum fluctuations. The source of the pair is an actual microscope image of the chain of Superconducting Quantum Interference Devices of the metamaterial sample in which the dynamical Casimir effect was studied. The speed of light in this material could be varied by changing the magnetic field through the SQUID loops.
