FIRST PROGRAMMABLE QUANTUM COMPUTER CREATED
Using a few ultracold ions, intense lasers and some electrodes, researchers have built the first programmable quantum computer. The new system, described in a paper to be published in Nature Physics, flexed its versatility by performing 160 randomly chosen processing routines.
Earlier versions of quantum computers have been largely restricted to a narrow window of specific tasks. [...]
