If quantum computers are ever going to perform all those expected feats of code-breaking and number crunching, then their component qubits---tiny ephemeral quantum cells held in a superposition of internal states---will have to be protected from intervention by the outside world. In other words, decoherence, the loss of the qubits´ quantum integrity, has to be postponed. Now theoretical physicists at the Joint Quantum Institute (JQI) and the University of Maryland have done an important...

With headlines proclaiming the discovery of the Higgs boson–the so-called God particle–particle physics has captured the imagination of the world, particularly among those who dwell on the nature of the cosmos. But this is only one puzzle seemingly solved in a universe of mysteries. In a recent paper in Physical Review Letters, Dartmouth physicists delve into another enigmatic particle. Majorana is a name whose very mention evokes a veil of mystery. On one level, it refers to a...

Scientists Say They've Found The Elusive Majorana Fermion

After a search that has lasted roughly three-quarters of a century, researchers believe they have at long last discovered evidence of an elusive particle that could be its own anti-particle. The existence of the particle, which is known as the Majorana fermion, was first predicted some 75 years ago, according to BBC News Science Correspondent Jonathan Amos. Now, a team of Dutch scientists believe that they have created an electronic device small enough to test for the Majorana, and they...

Exotic Quantum States: A New Research Approach
2011-10-03 09:23:13

Theoretical physicists of the University of Innsbruck have formulated a new concept to engineer exotic, so-called topological states of matter in quantum mechanical many-body systems. They linked concepts of quantum optics and condensed matter physics and show a direction to build a quantum computer which is immune against perturbations. The scientists have published their work in the journal Nature Physics. Three years ago a research team led by Sebastian Diehl and Peter Zoller presented...

  • A 'bachelor seal'; a young male seal which is prevented from mating by its herd's older males (mated bulls defending their territory).
This comes from the Russian word for 'bachelors.'
