An electronics technology that uses the "spin" - or magnetization - of atomic nuclei to store and process information promises huge gains in performance over today's electron-based devices. But getting there is proving challenging.

Using an "electric prism", scientists have found a new way of separating water molecules that differ only in their nuclear spin states and, under normal conditions, do not part ways. Since water is such a fundamental molecule ...

(Phys.org) —The ubiquitous classical digital computer encodes data in bits (a portmanteau of binary and digits) in either a 0 or 1 state. On the other hand, while a quantum computer also uses 0/1 data representation, these ...
Just as diamonds with perfect symmetry may be unusually brilliant jewels, the quantum world has a symmetrical splendor of high scientific value.
