The new phase of matter could be used to design even better quantum computers. Scientists have spotted a long hypothesized, never-seen-before states of matter in the laboratory for the first time. By firing lasers at an ultracold lattice of rubidium atoms scientists have prodded the atoms into a messy soup of quantum uncertainty known as a quantum spin liquid. The atoms in this quantum magnetic soup quickly became connected, linking up their states across the entire material in a process called quantum entanglement . This means that any change to one atom causes immediate changes in all of the others in the material; this breakthrough could pave the way for the development of even better quantum computers, the researchers said in a paper describing their findings Dec. 3 in the journal Science . "It is a very special moment in the field," senior author Mikhail Lukin, a professor of physics at Harvard University and the co-director of the Harvard Quantum...
