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 -
