Quantum one-way street in topological insulator nanowires

Posted by in categories: computing, nanotechnology, quantum physics

Very thin wires made of a topological insulator could enable highly stable qubits, the building blocks of future quantum computers. Scientists see a new result in topological insulator devices as an important step towards realizing the technology’s potential.

An international group of scientists have demonstrated that wires more than 100 times thinner than a can act like a quantum one-way street for electrons when made of a peculiar material known as a .

The discovery opens the pathway for new technological applications of devices made from topological insulators and demonstrates a significant step on the road to achieving so-called topological qubits, which it has been predicted can robustly encode information for a quantum computer.
