Quantum computer factors numbers, could be scaled up

Posted: 03 Mar 2016 11:57 AM PST

Researchers report that they have designed and built a quantum computer from five atoms in an ion trap. The computer uses laser pulses to carry out Shor's algorithm on each atom, to correctly factor the number 15. The system is designed in such a way that more atoms and lasers can be added to build a bigger and faster quantum computer, able to factor much larger numbers.

Asymmetry of an emotion

Though probably not at the top of the concerns of people affected by facial hemiparalysis, it's nonetheless a problem that should not be overlooked. Facial hemiparalysis not only makes it impossible to produce expressions, it also impairs the perception of expressions on other people's faces. A new study shows that this difficulty is probably related to an impairment of facial mimicry, a mechanism that helps us understand the emotions of others.
