Teleportation implementation of nondeterministic quantum logic operations by using linear optical elements
Xu‐Bo Zou, K. Pahlke, Wolfgang M. Mathis · Physical Review A · 2002
We present a feasible scheme to implement the nondeterministic quantum logic operation of Knill, Laflamme, and Milburn [Nature 409, 46 (2001)] by a teleportation technique. An entangled photon channel is generated by emitting two single photons into an asymmetric beam splitter. In order to generate the classical channel signal, two-photon detectors are needed.
