United Nations University, Hermann-Ehlers-Str. 10, 53113 Bonn, Germany(Dated: November 12, 2010)A parity meter projects the state of two qubits onto two subspaces with diﬀerent parities, thestates in each parity class being indistinguishable. It has application in quantum information forits entanglement properties. In our work we consider the electronic Mach-Zehnder interferometer(MZI) coupled capacitively to two double quantum dots (DQDs), one on each arm of the MZI.These charge qubits couple…
