Web⋆ In quantum mechanics a two-dimensional complex Hilbert space H is used for describing the angular momentum or “spin” of a spin-half particle (electron, proton, neutron, silver atom), which then provides a physical representation of a qubit. The polarization of a photon (particle of light) is also described by d= 2, so represents a qubit. Webquantum mechanics. Being the primitive concept of the theory, it is usually left undefined. However, by state we mean a list of some relevant charac-teristics of the system in question. More or less exact information about the quantities pertaining to the system are on this list, telling us how it is prepared.
WebFeb 23, 2024 · The effects of charging on the magnetic anisotropy energy (MAE) of rhenium atom in nitrogenized-divacancy graphene (Re@NDV) are investigated using density functional theory (DFT) calculations. High-stability and large MAE of 71.2 meV are found in Re@NDV. The more exciting finding is that the magnitude of MAE of a system can be …
