By exploiting entanglement, the quintessential "spooky" phenomenon in quantum mechanics, physicists have come up with a method for drawing tiny features on a microchip that would be impossible according to the classical theory of light. If it proves practical, the technique could enable chip designers to circumvent the so-called Rayleigh limit, a physical barrier that plagues chip manufactures much as the sound barrier used to bedevil aerospace engineers.
