Diamonds with minute flaws could play a crucial role in the future of quantum technology. For some time now, researchers at TU Wien have been studying the quantum properties of such diamonds, but only now have they succeeded in coupling the specific defects in two such diamonds with one another. This is an important prerequisite for the development of new applications, such as highly sensitive sensors and switches for quantum computers. The results of the research will now be published in the journal 'Physical Review Letters'. In search of a suitable quantum system - "Unfortunately, quantum states are very fragile and decay very quickly", explains Johannes Majer, head of the hybrid quantum research group, based at the Institute of Atomic and Subatomic Physics at TU Wien. For this reason, in-depth research is being carried out with the aim of finding quantum systems that can be used for technical applications. Even though there are some promising candidates with particular advantages, up until now there has been no system that fulfils all of the requirements simultaneously.
