Entanglement between static and flying qubits in an Aharonov-Bohm double electrometer.

By Henning Schomerus and John P Robinson

Abstract

. We consider the phase-coherent transport of electrons passing through an Aharonov�Bohm ring while interacting with a tunnel charge in a double quantum dot (representing a charge qubit) which couples symmetrically to both arms of the ring. For Aharonov�Bohm flux ΦAB = h/2e we find that electrons can only be transmitted when they flip the charge qubit's pseudospin parity an odd number of times. The perfect correlations of the dynamics of the pseudospin and individual electronic transmission and reflection events can be used to entangle the charge qubit with an individual passing electron
