Ultrafast computer processing speeds are possible with optical chirality logic gates that operate about a million times faster than existing technologies.
Processing devices based on polarized light run one million times faster than current technology.
Logic gates are the basic building blocks of computer processors. Conventional logic gates are electronic, working by shuffling around electrons. However, researchers have been developing light-based optical logic gates to meet the data processing and transfer demands of next-generation computing. Aalto University scientists developed new optical chirality logic gates that operate about a million times faster than existing technologies, offering ultrafast processing speeds.

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.
Additionally, the team 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/optical computing.

Tech Ping!...............
There will be a quiz about this tomorrow for all who are interested.
Interesting approach. I wonder if this could be expanded to more than bianary. Perhaps off, freq1, freq2, etc
A million times faster....... I WONDER WHAT THAT IS IN WHETSTONES AND DHRYSTONES?............
Oh joy.
MIGHT COME IN HANDY FOR QUANTUM MULTIPLE STATES...................
Sounds like this will help many people get their pron faster.
Just when we thought Moore’s Law was dying, something like this pops up.
More real estate for craptastic, Microsoft programmers to waste.

China has this technology now.
Windows will find ways to reduce this amazing capability to 386 speed.
This is “Stepford Wives” area.
Still won’t be fast enough to predict a woman changing her mind.....................
The only drawback to their use will be the constant dizziness and nausea caused by all those incredibly fast twisting and turnings during computer operation...
don’t expect new tech from the US.
the left has tailored education to deliberately exclude white and asian men from higher education (colleges).
Lotus Notes might even work properly then.
So might Windows......................Eventually.............
Oh great, true pocket supercomputers for all.
We really need the capability to hack EVERYTHING in seconds.
Bored ten year olds and launch codes readily hacked, just great. /s
State sponsored industrial espionage will be epic.
In fact this may just break the internet, as going off-line becomes the only way to protect data and systems.
With the varied “Probing” we have seen in the last few years our critical infrastructure should already be disconnected.
