🎇AIST: It demonstrates for the first time that the phase change of the electron wave reflects the internal structure of artificial atom

– Fixed the problem concerning the scattering phase of electrons for 20 years –

point

  1. We demonstrated that the phase shift of the electron wave scattered by artificial atom including many electrons shows behavior depending on the shape of the electron trajectory inside the artificial atom.
  2. The verification experiment was realized by conducting precise and reliable phase measurement using a two-way interferometer independently developed and improved.
  3. It is expected to be applied to quantum information devices such as qubits using elucidation of new physical phenomena by highly accurate phase measurement and phase control of electron wave.
