As the speaker at this year's Paul Bernays Lectures, Michel Devoret,?Chief Scientist at Google Quantum AI, discussed quantum information processing with superconducting circuits ¨C and took the time to find out about the variety of research activities in the ETH physics department.

Researchers in the Laboratory for Solid State Physics at ETH Zurich found evidence that bilayer graphene quantum dots may host a promising new type of quantum bit based on so-?called valley states.

Previous wisdom is debunked by new findings that solid-state qubits need to be super dilute in an ultra-clean material to achieve long lifetimes. Instead, cram lots of rare-earth ions into a crystal and some will form pairs that act as highly coherent qubits.

Researchers have succeeded in attaching electrodes to individual atomically precise nanoribbons, paving the way for precise characterization of the fascinating ribbons and their possible use in quantum technology.
