At the smallest scales, magnetism may not work quite the way scientists expected, according to a recent paper in Physical Review Letters by Rafal Oszwaldowski and Igor Zutic of the University at Buffalo and Andre Petukhov of the South Dakota School of Mines and Technology.
Using a convenient and flexible method for creating twin light beams, researchers from the National Institute of Standards and Technology (NIST) and the University of Maryland (UM) have produced “quantum images,” pairs of information-rich visual patterns whose features are “entangled,” or inextricably linked by the laws of quantum physics.
By combining advanced laser technologies in a new way, physicists at the National Institute of Standards and Technology (NIST) have generated microwave signals that are more pure and stable than those from conventional electronic sources.
Most important milestone in the direct measurement of the magnetic moment of the proton and its anti-particle has been achieved / Focusing the matter-antimatter symmetry.
Solar cells hold the potential to provide an efficient and environmentally-clean energy source. With the recent interest in alternative forms of energy, solar power is gaining importance, and so is research on solar cell...
Microscopes make tiny objects visible, as their name suggests. However, modern microscopes often do this in a round-about way, not by optically imaging the object with light, but by probing the surface with a fine, needle-like tip.
Quantum mechanics is famous for saying that a tree falling in a forest when there's no one there doesn't make a sound. Quantum mechanics also says that if anyone is listening, it interferes with and changes the tree. And...
The quantum bit (blue) is entangled with the auxiliary qubits (red). If an error occurs, the state of the defective quantum bit is corrected. (Graphics: Harald Ritsch)
Standing in front of a mirror, we can easily tell apart ourselves from our mirror image. The mirror does not affect our motion in any way. For quantum particles, this is much more complicated.
Quantum physicists from the University of Innsbruck have set another world record: They have achieved controlled entanglement of 14 quantum bits (qubits) and, thus, realized the largest quantum register that has ever been produced.
Nanoco Group plc (AIM: NANO), a world leader in the development and manufacture of cadmium-free quantum dots, announces that it has successfully produced the 1kg batch of red cadmium-free quantum dots (CFQD) specified by...
On April 8, 2011, the scientific community will celebrate the centennial of the discovery of superconductivity—the ability of certain materials to conduct electricity without resistance when cooled below a specific temperature.
Physicists at the National Institute of Standards and Technology (NIST) have demonstrated an electromechanical circuit in which microwaves communicate with a vibrating mechanical component 1,000 times more vigorously than ever achieved before in similar experiments.
Samsung Electronics Co. has succeeded in developing the world's first full-color display using quantum dots, paving the way for producing large displays that are brighter, cheaper and more advanced.
The sun provides more than enough energy for all our needs, if only we could harness it cheaply and efficiently. Solar energy could provide a clean alternative to fossil fuels, but the high cost of solar cells has been a major barrier to their widespread use.
