Atomic defects in diamonds can be used as quantum memories. Researchers at TU Wien for the first time have succeeded in coupling the defects in various diamonds using quantum physics.
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 (“Coherent Coupling of Remote Spin Ensembles via a Cavity Bus”).
