How Chiral Spintronics Could Transform Computing

How Spintronics Could Revolutionize Computing

Progressively, the world of hardware computing is starting to look beyond silicon chips, or even classical forms of binary computing altogether.
This is because the usual chips and memory in our computers and data centers are getting increasingly difficult to build, with the latest generation having transistors barely a few nanometers in size.
Another factor is that energy consumption is becoming an issue as the demand for computing power, particularly for AI systems, continues to grow.
There are many proposed solutions, with quantum computing and photonics being the most prominent options to either reduce the demand for computing or make it faster and less energy-intensive.
Another is spintronics, which utilizes the spin of electrons, a quantum characteristic, instead of the electric current (the flow of electrons).

Advantages and Potential Applications of Spintronics

Electronic components, such as transistors, are traditionally built from silicon and rely on semiconductors. The 0 and 1 signals in binary indicate the passing or blocking of an electric current.
An alternative way to perform computation is through spintronic devices, which run on the spin of electrons (a fundamental quantum characteristic) rather than the electric current (the flow of electrons).
