human-made diamond

GLITZY HARDWARE  A new kind of human-made diamond (the clear material across the middle of this optical microscope image, measuring about 4 by 10 millimeters) laced with silicon and boron could be used to build better quantum memory devices.

piston illustration

POWER THROUGH  Car engines operate using pistons (illustrated), which convert the heat from burning fuel into motion. Friction decreases the efficiency of such engines, but quantum machines can evade that limitation.

a Newton's cradle

GOT THAT SWING  Metal spheres in a Newton’s cradle (shown) swing back and forth rhythmically. The toy has inspired a quantum experiment where atoms replace the balls.
