Quantum information procession with fermions based on charge detection

This paper proposes a fermionic linear optical schemefor the teleportation and entanglement concentration viaentanglement swapping based on charge detection. It also proves thatthis method is useful in generating entangled states such as GHZstates, W states, and cluster states by using fermionic polarizingbeam splitters and single spin rotations assisted by a parity check onthe fermionic qubits. This scheme is nearly deterministic (i.e.,with 100% successful probability) and does not need the jointBell state measurement required in the previous schemes.
