Ideal refocusing of an optically active spin qubit under strong hyperfine interactions

Nature Nanotechnology, Published online: 26 January 2023; doi:10.1038/s41565-022-01282-2Optically active semiconductor quantum dots have so far suffered from nuclear inhomogeneity limiting all dynamical decoupling measurements to a few microseconds. Lattice-matched GaAs–AlGaAs quantum dots now enable decoupling schemes to achieve a 0.11 ms spin coherence...

Three-dimensional topological magnetic monopoles and their interactions in a ferromagnetic meta-lattice

Nature Nanotechnology, Published online: 23 January 2023; doi:10.1038/s41565-022-01311-0Topological magnetic monopoles are non-local spin textures that are robust to thermal and quantum fluctuations, but they are difficult to study at the nanoscale in real space. Now, soft X-ray vector ptycho-tomography is demonstrated to determine the three-dimensional...
