Quantum computing with quantum-Hall edge state interferometry

摘要: Electron interferometers based on Hall edge states proved to be robust demonstrators of the coherent quantum dynamics carriers. Several proposals expose their capability build and control entanglement exploit them as building block for computing devices has been presented. Here, we review time-dependent numerical modeling operating at single-carrier level integer filling factor (FF). By defining qubit state either spatial localization (at FF 1) or Landau index 2) a single carrier propagating in state, show how generic one-qubit rotation can realized. proper design 2DEG potential landscape, an entangling two-qubit gate implemented by exploiting Coulomb interaction, thus realizing universal set gates. We also assess shape confining affects visibility transformations.
