Controlling the interaction between light and matter

(PhysOrg.com) -- "One of the most exciting things about this is that it gives us nice, clean control over the interaction between light and matter," William Kelly tells PhysOrg.com. "Our technique has the potential to give ...

NIST Detector Counts Photons With 99 Percent Efficiency

(PhysOrg.com) -- Scientists at the National Institute of Standards and Technology have developed the world's most efficient single photon detector, which is able to count individual particles of light traveling through fiber ...

Creating a quantum gas

(PhysOrg.com) -- "One of the many reasons people study ultracold gases is for their potential as model quantum systems," Deborah Jin tells PhysOrg.com. "There is a need to model quantum many-body systems because a lot of ...

New light shed on old dispute between Einstein and Bohr

In classical physics there are no uncertainties - the properties of matter on an atomic level are deterministic, that is to say predetermined. The theories of quantum mechanics, however, only say something about how likely ...

Physicists make discovery in quantum mechanics

(Santa Barbara, Calif.) -- 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.

Quantum measurements: Common sense is not enough

(PhysOrg.com) -- In 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 are carried ...
