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.

Will this be better than my upgraded 386 w/ an overdrive processor?
Good thing I got optical switches on my keyboard and mouse so I can keep up. /sarcasm
Indeed. These days, unless you're doing pretty damned hi-powered computation, it's not the CPU that is slowing you down. It is memory, bandwith and storage latencies, and other bottlenecks. Modern CPUs are blazingly fast. Also, few programs seem to know how to really make use of multiple cores efficently.
My desktop has 16 cores. Most of the time all but one or two of them are effectively idle.
Is that even a thing anymore? I dealt with Notes a lifetime ago.
I certianly hope so!
Ultrafast mistakes yeah that’s what we need Hal’s light comes back on.
Moore’s “Law” was about 100x increase per decade. 1,000,000x is about 3 decades worth.
Can you please add me to your tech ping list
This means you can post misspelled words at FreeRepublic faster then ever.
If this is true, and China has it, it is very, very bad.
Okay, I’m confused.
Aalto University in Finland.
The researchers are all Chinese.
WTF?
Sadly for me it is a bane of my existence.
In theory by early summer it will finally go away then there will be much rejoicing.
Getting the written approval to delete the VM would be a great present.
Well, it’s been dead for more than a decade IMO, so this would help catch back up.
With Elon Musk working on implanting chips in our brain, one of these light chips would make us old people seem pretty smart.
Interesting.
This may be the leap forward in real-world processing that quantum computing was hoping to be.

Wish I hung on to my $.40US shares!
...but the only ones that can afford it will be the government spying on you with your own tax dollars.
