Finland Develops Optical Computer Process 1-M Times Faster Than Current Tech

Aalto University in Espoo, Finland has developed optical chirality logic gates that operate about a million times faster than existing technologies, thus offering ultrafast processing speeds, SciTech Daily reported and could revolutionize quantum computing technology worldwide.

This new approach, which is described in a paper published in the journal Science Advances, uses circularly polarized light as the input signal.

The logic gates are made from crystalline materials that are sensitive to the handedness of a circularly polarized light beam – that is, the light emitted by the crystal depends on the handedness of the input beams.

This serves as the basic building block for one type of logic gate (XNOR), and the remaining types of logic gates are built by adding filters or other optical components.

The Aalto University team, comprised of 11 members demonstrated that a single device could contain all of their chirality logic gates operating simultaneously in parallel. This is a significant advance over existing logic gates, which can only carry out a single logic operation at a time.

Simultaneous parallel logic gates could be used to build complex, multifunctional logic circuits.

Finally, the team demonstrated that the chirality logic gate could be controlled and configured electronically, a necessary step for hybrid electrical or optical computing. The new process could make simulations at the quantum level, thus improving current knowledge about subatomic particles.
