Quantum physics is on the brink of many technological breakthroughs. However, the main obstacle is finding the right way to couple and precisely control a sufficient number of quantum systems (e.g. individual atoms). A team of researchers from TU Wien and Harvard University has found a new way to manipulate the quantum universe via tiny mechanical vibrations.

“Normally, diamonds are made exclusively of carbon, but adding silicon atoms in certain places creates defects in the crystal lattice where quantum information can be stored”, says Professor Peter Rabl from TU Wien. These microscopic flaws in the crystal lattice can be used like a tiny switch that can be switched between a state of higher energy and a state of lower energy using microwaves.

Together with a team from Harvard University, Peter Rabl’s research group has developed a new idea to achieve the targeted coupling of quantum memories within the diamond. One by one they can be built into a tiny diamond rod measuring only a few micrometres in length. Then this rod can then be made to vibrate, however, these vibrations are so small that they can only be described using quantum theory. It is through these vibrations that the silicon atoms can form a quantum-mechanical link to each other. (1)
