Like any task, there is an easy and a hard way to control atoms and molecules as quantum systems, which are driven by tailored radiation fields. More efficient methods for manipulating quantum systems could help scientists realize the next generation of technology by harnessing atoms and molecules to create small but incredibly powerful devices such as molecular electronics or quantum computers. Of course, controlling quantum systems is as painstaking as it sounds, and requires scientists...

A quantum computer can solve tasks where a classical computer fails. The question how one can, nevertheless, verify the reliability of a quantum computer was recently answered in an experiment at the University of Vienna. The conclusions are published in the reputed scientific journal Nature Physics. The harnessing of quantum phenomena, such as superposition and entanglement, holds great promise for constructing future supercomputers using quantum technology. One huge advantage of such...

Creating Matter That Behaves Like Luke Skywalker's Light Saber

redOrbit Staff & Wire Reports - Your Universe Online Scientists from Harvard University and the Massachusetts Institute of Technology (MIT) have joined forces to create a never-before-seen form of matter that is said to behave like the legendary light sabers of Star Wars fame. Harvard physics professor Mikhail Lukin, MIT physics professor Vladan Vuletic and their colleagues were able to coax photons into binding together to form what they describe as “photonic molecules.” In...

Johannes Gutenberg Universitaet Mainz Hybrid technology makes possible highly reliable transmission of photonic qubits By means of the quantum-mechanical entanglement of spatially separated light fields, researchers in Tokyo and Mainz have managed to teleport photonic qubits with extreme reliability. This means that a decisive breakthrough has been achieved some 15 years after the first experiments in the field of optical teleportation. The success of the experiment conducted in Tokyo...

Quantum research pushes boundary by testing micro theory for macro objects Since Erwin Schroedinger's famous 1935 cat thought experiment, physicists around the globe have tried to create large scale systems to test how the rules of quantum mechanics apply to everyday objects. Researchers at the University of Calgary recently made a significant step forward in this direction by creating a large system that is in two substantially different states at the same time. Until this point,...

Heat Radiation Of Small Objects Is Beyond Planck's Equations
2013-07-11 11:20:03

Vienna University of Technology Objects that are smaller than the wavelength of thermal radiation cannot radiate heat efficiently. A generalized theory of thermal radiation has now been experimentally confirmed at the level of a single object at the Vienna University of Technology. All the objects around us emit thermal radiation. Usually, this radiation can be described very accurately using Planck's law. If, however, the radiating object is smaller than the thermal wavelength, it...
