But the quantum world is bizarrely different. Two metal plates, placed almost infinitesimally close together, spontaneously attract each other. What seems like magic is known as the Casimir force, and it has been well-documented in experiments. The cause goes to the heart of quantum physics: Seemingly empty space is not actually empty but contains virtual particles associated with fluctuating electromagnetic fields. These particles push...

Scientists have "entangled" the motions of pairs of atoms for the first time.

Room-temperature entanglement seems to be a by-product of the process of harvesting light.

Of related interest, in the light of recent research, is recognition that the source of energy in biological motion -- the capacity of muscles to generate pulling force -- may be explicable in terms of quantum tunnelling. Living cells are indeed capable of "burning" biological fuel to generate energy for muscle contraction. It is enzymes which accelrate the rate of chemical reactions -- with billion-fold enhancements of chemical...

Entangled... What if electrons were not really elementary, but were formed at the ends of long "strings" of other, fundamental particles? ... Could the entire universe be modelled in a similar way?

As Maccone pictures it, while broken eggs may reassemble themselves, we do not see this happen because the information about such events is not preserved. It's as if such information is, in effect, erased from our memory.

While physicists struggle to get quantum computers to function at cryogenic temperatures, other researchers are saying that humble algae and bacteria may have been performing quantum calculations at life-friendly temperatures for billions of years. The evidence comes from a study of how energy travels across the light-harvesting molecules involved in photosynthesis. The work has culminated this week in the extraordinary announcement that...

Scientists in China have succeeded in teleporting information between photons further than ever before. They transported quantum information over a free space distance of 16 km, much further than the few hundred meters previously achieved, which brings us closer to transmitting information over long distances without the need for a traditional signal.
