QUANTUM entanglement—the mysterious phenomenon that allows a quantum
state to be transmitted huge distances apparently instantaneously—may
never allow Scotty to beam you up, but it could do wonders for chip
manufacture.
Scientists in Spain and Sweden say that by using entangled photons, chip
makers may be able to overcome the physical barrier to making smaller, faster
circuits.
Microchips are made by shining light through a “mask” to project a circuit
pattern onto light-sensitive chemicals on the surface of a wafer of silicon. The
smaller these circuits can be made, the faster the chip runs and the more data…
