Abstract: | This paper proposes a fermionic linear optical scheme
for the teleportation and entanglement concentration via
entanglement swapping based on charge detection. It also proves that
this method is useful in generating entangled states such as GHZ
states, W states, and cluster states by using fermionic polarizing
beam splitters and single spin rotations assisted by a parity check on
the fermionic qubits. This scheme is nearly deterministic (i.e.,
with 100\% successful probability) and does not need the joint
Bell state measurement required in the previous schemes. |
