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...

Quantum Inverted Pendulum
2013-08-28 08:18:43

Georgia Institute of Technology A simple pendulum has two equilibrium points: hanging in the "down" position and perfectly inverted in the "up" position. While the "down" position is a stable equilibrium, the inverted position is definitely not stable. Any infinitesimal deviation from perfectly inverted is enough to cause the pendulum to eventually swing down. It has been known for more than 100 years, though, that an inverted pendulum can be stabilized by vibrating the pivot point....

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...

Researchers Discover Atomic Clock Can Simulate Quantum Magnetism
2013-08-09 11:33:49

National Institute of Standards and Technology (NIST) Researchers at JILA have for the first time used an atomic clock as a quantum simulator, mimicking the behavior of a different, more complex quantum system. Atomic clocks now join a growing list of physical systems that can be used for modeling and perhaps eventually explaining the quantum mechanical behavior of exotic materials such as high-temperature superconductors, which conduct electricity without resistance. All but the...

Resonance In 'Artificial Atoms' Control Quantum Communication
2013-08-06 12:26:15

University of Copenhagen - Niels Bohr Institute Researchers at the Niels Bohr Institute, together with colleagues in the US and Australia, have developed a method to control a quantum bit for electronic quantum communication in a series of quantum dots, which behave like artificial atoms in the solid state. The results have been published in the scientific journal Physical Review Letters. In a conventional computer, information is made up of bits, comprised of 0's and 1's. In a quantum...

D-Wave Quantum Optimizer Quantum Computing

redOrbit Staff & Wire Reports - Your Universe Online Quantum computing company D-Wave Systems has made impressive inroads in demonstrating how their quantum optimizer can have real-world applications. The company has sold their system to Google and Lockheed Martin in recent months, and appears to have made another step forward in demonstrating that their machine is not performing classical simulated annealing. Annealing is a process in which a physical system slowly relaxes, and...


Word of the Day
humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
