摘要: We propose the schemes for implementing hyperentangled state analysis and generating four-electron high entangled states (including cluster state, |χ> state, and symmetric Dicke state) based on the charge detection of free electrons. These schemes are deterministic and rely only on charge detection and single-spin rotations. This method, which uses noninteracting electrons, is not only efficient but also saves on quantum resources.
