Making computers talk faster - without wires

As computers become more powerful - especially with the rise of quantum and neuromorphic (brain-like) systems - one big problem keeps growing: how to move information quickly and efficiently between all those tiny processing units.

Today’s chips rely on wired connections, but those wires take up space, use power and slow things down.

A study led by Kosala Herath (Department of Physics, Lund University, Sweden) and Professor Malin Premaratne (Monash Electrical and Computer Systems Engineering) explores a radical alternative: wireless communication inside the chip itself.

Their team has designed a terahertz (ultra-high frequency) wireless system that uses a special transmitter and a nano-scale receiver made from advanced semiconductor materials. By precisely controlling how electrons move through these materials, they’ve created a system that can send data between parts of a chip at lightning speed, with minimal interference and far less energy.

In short, they’re cutting the wires inside the world’s fastest computers.

This could be a game-changer for how future quantum and AI processors are built: faster, more scalable and more energy-efficient.
