Physicists at UC Santa Barbara have made an important advance in electrically controlling quantum states of electrons, a step that could help in the development of quantum computing. The work is published ...
Quantum measurements: Common sense is not enough
Jul 22, 2009 |
4.1 / 5 (19) |
19
(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 ...
Entanglement without Classical Correlations
Aug 27, 2008 |
4.1 / 5 (60) |

(PhysOrg.com) -- For the first time, scientists have successfully operated a quantum gate between two remote particles of matter, marking an important step toward the development of a quantum computer. In ...
Physicists working up from atoms to Schrodinger's cat
Jan 28, 2009 |
4.2 / 5 (19) |
1
(PhysOrg.com) -- Schrodinger's cat, a macroscopic object that is both alive and dead at the same time, illustrates the strangeness of quantum mechanics. While such quantum properties have been widely observed for electrons ...

An international team of physicists from the United States and China this week offered a new theory to both explain and predict the complex quantum behavior of a new class of high-temperature superconductors.
It's Easier to Observe the Failure of Local Realism than Previously Thought
Mar 04, 2009 |
4.3 / 5 (41) |
199
(PhysOrg.com) -- Local realism is something we live with every day, even if we don’t realize it. The principle of local realism combines two assumptions: locality and realism. Locality says that distant objects cannot directly ...
