Physicists have demonstrated a quantum machine that could reduce errors in quantum computers by ensuring that the qubits they use remain in their initial state before a calculation starts.

Seong Jim Kim and Myoung-Woon Moon of the Korea Institute of Science and Technology have developed a device that can “vacuum” up tiny pieces of plastic floating on the surface of a body of water.

Roughing up the surfaces of particles in a colloidal system can smooth its transition into a glassy state.

In one of his annus mirabilis papers, Einstein explained the photoelectric effect by considering light as a stream of energy quanta—which were later called photons.

Noise is typically detrimental to quantum effects, but simulations suggest that it can boost entanglement under certain conditions.
