The ability to exploit the extraordinary properties of quantum mechanics in novel applications, such as a new generation of super-fast computers, seems to come closer following with recent breakthroughs by an international team led by researchers from the University of New South Wales.

In the two breakthroughs, written up in the international journals Nano Letters and Applied Physics Letters, researchers have for the first time demonstrated two ways to deliberately place an electron in a nano-sized device on a silicon chip.
The achievements set the stage for the next crucial steps of being able to observe and then control the electron’s quantum state or “spin”, to create a quantum bit. Multiple quantum bits coupled together make up the processor of a quantum computer.
