Optical computers run a million times faster than conventional computers, study revealsThe processors in a computer are made up of logic gates, which run binary routines, the actual 1 and 0's of computer calculation.New optical logic gatesA new optic chirality logic gates designed and developed by a team of scientists at AALTO University are being run at about a million times faster than previous logic gates.AbstractThe ever-growing demand for faster and more efficient data transfer and processing has brought optical computation strategies to the forefront of research in next-generation computing.By exploiting the crystal symmetry–enabled well-known chiral selection rules, we demonstrate the viability of the concept in bulk silica crystals and atomically thin semiconductors and create ultrafast (<100-fs) all-optical chirality logic gates (XNOR, NOR, AND, XOR, OR, and NAND) and a half adder.We also validate the unique advantages of chirality gates by realizing multiple gates with simultaneous operation in a single device and electrical control."
