Tiny optical cavity could make quantum networks possible

Engineers at Caltech have shown that atoms in optical cavities—tiny boxes for light—could be foundational to the creation of a quantum internet. Their work was published on March 30 by the journal Nature.

Researchers successfully demonstrate a quantum gate in silicon

Milestone on the path to the quantum computer: Scientists of the University of Konstanz, Princeton University, and the University of Maryland have developed a stable quantum gate for two-quantum bit systems made of silicon. ...

Quantum computation: Fragile yet error-free

In a close collaborative effort, Spanish and Austrian physicists have experimentally encoded one quantum bit (qubit) in entangled states distributed over several particles and for the first time carried out simple computations ...
