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.
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.
