Magnets in a spin bath
Is quantum mechanics relevant to everyday life? Latest scientific evidence suggests that it is. A paper published in Science based on research from the Paul Scherrer Institute (PSI) in Switzerland and others, reports how quantum computers behave as if they are isolated devices. The extent to which they do this can be regulated by the environment... view more... (2005-04-15)
Physicists at UC Santa Barbara make discovery in quantum mechanics
Physicists 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 Nature. view more (2009-09-24)
Experiments at UCSB push quantum mechanics to higher levels
Scientists 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 findings are published in the August 7 issue of Science. view more (2009-08-12)
Quantum paradox directly observed -- a milestone in quantum mechanics
In 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 in Japan has moved one of the fundamental paradoxes in quantum mechanics into the lab for experimentation and observed some of the 'spooky action of quantum... view more...

Rutgers researchers 'rewrite the book' in quantum statistical physics
An important part of the decades-old assumption thought to be essential for quantum statistical physics is being challenged by researchers at Rutgers, The State University of New Jersey, and colleagues in Germany and Italy. view more (2006-02-10)
Quantum ghosts are helpful
The idea that far distant particles can somehow 'talk' to each other worried Einstein so much that he called it 'spooky action at a distance'. view more (2009-04-28)
Building a better qubit
Exploiting quantum mechanics for transmitting information is a tantalizing possibility because it promises secure, high speed communications. view more (2009-10-06)
Q is for quantum and 'Q-life'
As the world celebrates Charles Darwin, who was born 200 years ago, physicists can be forgiven a certain jealousy at the spotlight being placed on his profound legacy. view more (2009-07-08)
Imaging quantum entanglement
An international team including scientists from the London Centre for Nanotechnology (LCN) today publishes findings in the journal 'Proceedings of the National Academy of Sciences' (PNAS) demonstrating the dramatic effects of quantum mechanics in a simple magnet. view more (2007-09-24)
Researchers unite to distribute quantum keys
Researchers from across Europe have united to build the largest quantum key distribution network ever built. view more (2009-07-02)
UCSB researchers make milestone discovery in quantum mechanics
Researchers at UC Santa Barbara have recently reached what they are calling a milestone in experimental quantum mechanics. view more (2008-08-06)
Computer hackers R.I.P. -- making quantum cryptography practical
Quantum cryptography, a completely secure means of communication, is much closer to being used practically as researchers from Toshiba and Cambridge University's Cavendish Laboratory have now developed high speed detectors capable of receiving information with much higher key rates, thereby able to receive more information faster. view more (2009-04-30)
Quantum gas microscope offers glimpse of quirky ultracold atoms
Physicists at Harvard University have created a quantum gas microscope that can be used to observe single atoms at temperatures so low the particles follow the rules of quantum mechanics, behaving in bizarre ways. view more (2009-11-05)
Evidence of macroscopic quantum tunneling detected in nanowires
A 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 superconducting wire is able to "tunnel" as a pack from a state with a higher electrical current to one with a notably lower current, providing more... view more...

Dream of quantum computing closer to reality as mathematicians chase key breakthrough
The ability to exploit the extraordinary properties of quantum mechanics in novel applications, such as a new generation of super-fast computers, has come closer following recent progress with some of the remaining underlying mathematical problems. view more (2008-12-22)
Silicon chips for optical quantum technologies
A team of physicists and engineers has demonstrated exquisite control of single particles of light - photons - on a silicon chip to make a major advance towards the long sought after goal of a super-powerful quantum computer. view more (2008-03-28)
New device from CU physicist tests uncertainty principle to unprecedented level — and shows that looks can cool
In the submicroscopic world - the domain of elementary particles and individual atoms - things behave in the strange, counter-intuitive fashion governed by the principles of quantum mechanics. view more (2006-09-25)
Loopy photons clarify 'spookiness' of quantum physics
Researchers at the National Institute of Standards and Technology (NIST) and the Joint Quantum Institute (NIST/University of Maryland) have developed a new method for creating pairs of entangled photons, particles of light whose properties are interlinked in a very unusual way dictated by the rules of quantum physics. view more (2008-03-19)
UCLA physicists create world's smallest incandescent lamp
In an effort to explore the boundary between thermodynamics and quantum mechanics - two fundamental yet seemingly incompatible theories of physics - a team from the UCLA Department of Physics and Astronomy has created the world's smallest incandescent lamp. view more (2009-05-07)
Delft University of Technology rotates electron spin with electric field
Researchers at the Delft University of Technology's Kavli Institute of Nanoscience and the Foundation for Fundamental Research on Matter (FOM) have succeeded in controlling the spin of a single electron merely by using electric fields. view more (2007-11-02)
