Plenty of nothing A hole new quantum spin: "
Known as a hole quantum wire, it exploits gaps – or holes - between electrons. The relationship between electrons and holes is like that between electrons and anti-electrons, or matter and anti-matter.

The holes can be thought of as real quantum particles that have an electrical charge and a spin. They exhibit remarkable quantum properties and could lead to a new world of super-fast, low-powered transistors and powerful quantum computers.

Associate Professor Alex Hamilton and Dr Adam Micolich, who lead the UNSW Quantum Electronic Devices group in Sydney, Australia, say the discovery that the holes can carry an electrical current puts the team at the front of its field in the quantum electronics revolution. "
