“The phenomenon of coherent population trapping (CPT) of an atom (or solid state “artificial atom”), and the associated effect of electromagnetically induced transparency (EIT), are clear demonstrations of quantum interference due to coherence in multilevel quantum systems. We report observation of CPT in a superconducting phase qubit by simultaneously driving two coherent transitions in a Î-type configuration, utilizing the three lowest lying levels of a local minimum of a phase qubit. We observe 60(±7)% suppression of the excited state population under conditions of CPT resonance. We present data and matching theoretical simulations showing the development of CPT in time. Finally, we used the observed time dependence of the excited state population to characterize quantum dephasing times of the system.”

“We present a scheme for obtaining stable Casimir suspension of dielectric nontouching objects immersed in a fluid, validated here in various geometries consisting of ethanol-separated dielectric spheres and semi-infinite slabs. Stability is induced by the dispersion properties of real dielectric (monolithic) materials. A consequence of this effect is the possibility of stable configurations (clusters) of compact objects, which we illustrate via a molecular two-sphere dicluster geometry consisting of two bound spheres levitated above a gold slab. Our calculations also reveal a strong interplay between material and geometric dispersion, and this is exemplified by the qualitatively different stability behavior observed in planar versus spherical geometries.”

“Homeopathic bombs are comprised of 99.9% water but contain the merest trace element of explosive. The solution is then repeatedly diluted so as to leave only the memory of the explosive in the water molecules. According to the laws of homeopathy, the more that the water is diluted, the more powerful the bomb becomes.
‘It was only a matter of time before these people got hold of the material that they needed to make these bombs,’ said former UN weapons inspector, Hans Blix, ‘The world is a much more dangerous place with the advent of these Weapons of Mass Dilution.'”
