Ultracoherent mechanical devices

Similarly, a phononic crystal is a fabricated object with a repeating pattern that gives it a particularly useful property – a bandgap that forbids the propagation of motion at certain frequencies. This allows us to…

Innovative chip built by UCPH physicists resolves quantum headache

Quantum physicists at the University of Copenhagen are reporting an international achievement for Denmark in the field of quantum technology. By simultaneously operating multiple spin qubits on the same quantum chip,…
