Abstract
A method for interaction-free entanglement of quantum bits in quantum computers, in which the quantum bits to be entangled are available in the state Ψwith arbitrarily real phases φ and θ as an elementary quantum system. The two quantum bits () and () are localized in spatial regions () and (') and surrounded by switchable sheaths () and (′) preferably a superconductor with the jump temperature T. The switchable sheaths, in the activated state, completely displace a global, homogeneous magnetic field Bfrom the spatial regions () and (′). In the inactivated state, the switchable sheaths do not shield the spatial regions () and (′). If the switchable sheaths are switched from the activated state into the inactivated state while observing the boundary condition (R), as a result of this, the two quantum bits () and () are transferred into the entangled state Ψ.
