Two black diamonds on a superconducting chip (12x4mm). The wiggly line is a resonator, coupling the two diamonds.
Atomic defects in diamonds can be used as quantum memories. 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.
“Unfortunately, quantum states are very fragile and decay very quickly,” explains Johannes Majer, head of the hybrid quantum research group, Institute of Atomic and Subatomic Physics at TU Wien...
