Experimental demonstration of Berry's Phase in a solid-state qubit Zürich|Waterloo|Sherbrooke|Yale In Science, arXiv preprint, and concomitant ETH-Zürich report "Geometry for Quantum Computers," researchers in collaboration with the Quantum Device Lab have demonstrated Berry's phase in solid-state circuit quantum electrodynamics, an approach which is inherently robust against certain types of errors. "Geometric phase has been argued to have potential fault tolerance. We demonstrate the controlled accumulation of geometric phase, Berry's phase, in a superconducting qubit, manipulating the qubit geometrically using microwave radiation, and observe the accumulated phase in an interference experiment.
