Bringing Cheaper, 'Greener' Lighting to Market With Inkjet-Printed Hybrid Quantum Dot LEDs
June 4, 2013 — It's not easy going green. For home lighting applications, organic light emitting diodes (OLEDs) hold the promise of being both environmentally friendly and versatile. Though not as efficient as ... > full story -
More Precision from Less Predictability: A New Quantum Trade-Off
May 29, 2013 — Researchers in Australia have demonstrated that, contrary to what the Heisenberg uncertainty relation may suggest, particle properties such as position and momentum can be measured simultaneously ... > full story -
Klein Tunneling: Coupled Particles Cross Energy Wall
May 29, 2013 — A new model demonstrates that it is possible for two particles to cross an energy barrier together, where a single particle could not. For the first time, a new kind of so-called Klein tunneling -- ... > full story -
Just How Secure Is Quantum Cryptography?
May 28, 2013 — Unlike classical encryption, quantum communication systems are known to offer the promise of virtually unbreakable encryption. Now, new research on this topic is shaking up the long-held notion that ... > full story -
Einstein's 'Spooky Action' Common in Large Quantum Systems
May 28, 2013 — Mathematician have shown that entanglement -- what Einstein termed "spooky action at a distance" -- is actually prevalent in large quantum systems and have identified the threshold at which it ... > full story -
Hydrogen Atoms Under the Magnifying Glass: Nodal Structures of Electronic States of Hydrogen Atom Directly Observed
May 27, 2013 — Researchers have succeeded in building a microscope that allows magnifying the wave function of excited electronic states of the hydrogen atom by a factor of more than 20,000, leading to a situation ... > full story -
Helicopter Light-Beams: New Tool for Quantum Optics
May 27, 2013 — A light wave oscillates perpendicular to its propagation direction -- that is what students learn in school. However, scientists in Austria have now performed atomic physics experiments with light ... > full story -
A Quantum Simulator for Magnetic Materials
May 23, 2013 — Physicists have developed a quantum simulator that allows arranging atoms in a way that they mimic the behavior of electrons in magnetic materials. The experiment opens up the possibility of ... > full story -
Quest for Quantum Computing Advanced
May 23, 2013 — Scientistst investigating the properties of ultra-thin films of new materials are helping bring quantum computing one step closer to ... > full story -
Optics: Statistics Light the Way
May 22, 2013 — A revelation of how photoreceptive cells in the eye distinguish between different light sources could pave the way for a novel class of optical ... > full story
