Researchers from Delft University of Technology successfully manipulated the atomic nucleus of a single titanium atom, causing it to interact with an electron in the outer shell. This groundbreaking research, published in Nature Communications, holds promise for storing quantum information securely within the nucleus. The team discovered that the nucleus’ spin, or magnetism, can be influenced by an electron’s spin through a weak hyperfine interaction. The researchers were able to push the electron spin out of equilibrium using a voltage pulse, validating Schrödinger’s predictions. The observed results align with mathematical calculations, showing no loss of quantum information. This study opens the door to storing quantum information in nuclei, a significant advancement in quantum research.
