Progress towards quantum computing?

[popeyespappy]

The promise of quantum computing is largely predicated on whether or not physicists can keep quantum bits, or “qubits,” from slipping out of their two-state existence due to quantum fluctuations. This fundamental limitation has spawned research into different approaches to creating qubits.

The latest comes from Rice University, where physicists have created a device called a “quantum spin Hall topological insulator” which acts are a tiny electron superhighway designed for increased fault-tolerance.

The researchers claim that the device is one of the building blocks needed to create quantum particles that store and manipulate data.
