We put forward a fast scheme for one-step generation of maximally entangled Greenberger–Horne–Zeilinger (GHZ) states by superconducting quantum interference devices (SQUIDs) in cavity via Raman interaction. The scheme only requires a quantized cavity field and classical microwave pulses. One of the key advantages of our Raman-interaction scheme is that an improvement of overcoming decoherence for the preparation of the desired GHZ states can be achieved.

The talk centers around the question: Can general-relativistic description of physical reality be considered complete? On the way I argue how – unknown to many a physicists, even today – the "forty orders of magnitude argument" against quantum gravity phenomenology was defeated more than a quarter of a century ago, and how we now stand at the possible verge of detecting a signal for the spacetime foam, and studying the gravitationally-modified wave particle duality using superconducting quantum interference devices.
