— 24 Sep 2009 08:41 | PhysicsPhysicists at UC Santa Barbara have made an important advance in quantum mechanics using a superconducting electrical circuit. The finding is reported in this week's issue of the journal…
Experiments at UCSB push quantum mechanics to higher levels
— 12 Aug 2009 12:26 | TechnologyScientists at UC Santa Barbara have devised a new type of superconducting circuit that behaves quantum mechanically - but has up to five levels of energy instead of the usual two. The…
Quantum measurements: Common sense is not enough
— 22 Jul 2009 17:00 | PhysicsIn comparison to classical physics, quantum physics predicts that the properties of a quantum mechanical system depend on the measurement context, i.e. whether or not other system measurements…

Evidence of macroscopic quantum tunnelling detected in nanowires
— 28 May 2009 14:12 | TechnologyA team of researchers at the University of Illinois has demonstrated that, counter to classical Newtonian mechanics, an entire collection of superconducting electrons in an ultrathin…
Quantum ghosts are helpful
— 27 Apr 2009 14:14 | PhysicsThe idea that far distant particles can somehow 'talk' to each other worried Einstein so much that he called it 'spooky action at a distance.' Having confirmed its existence, scientists…
Quantum paradox directly observed - a milestone in quantum mechanics
— 4 Mar 2009 15:30 | PhysicsIn quantum mechanics, a vanguard of physics where science often merges into philosophy, much of our understanding is based on conjecture and probabilities, but a group of researchers…
