In today’s Science Express, the advance online publication of the journal Science, researchers report a series of experiments that mark an important step toward understanding a longstanding fundamental physics problem of quantum mechanics. The scientists presented their findings at the annual meeting of the American Physical Society here this week.

RIKEN, NEC Corporation, and JST (“Japan Science and Technology Agency”) have successfully demonstrated a laser emission from one artificial atom by coupling superconducting quantum bits (“qubits”) to a resonator. The lasing effect was achieved by an extremely simple system - a single “atom” coupled to a resonator - and represents a world first in the use of a superconducting qubit as an artificial atom to generate lasing photons.

An international team, including scientists from the London Center for Nanotechnology, has detected a hidden magnetic "quantum order" that extends over chains of 100 atoms in a ceramic without classical magnetism.

A team of European scientists has proved within an ESA study that the weird quantum effect called entanglement remains intact over a distance of 144 kilometres.
