Quantum Teleportation of Optical Quantum Gates

Phys Rev Lett. 2003 Mar 21;90(11):117901. doi: 10.1103/PhysRevLett.90.117901. Epub 2003 Mar 17.


We show that a universal set of gates for quantum computation with optics can be quantum teleported through the use of EPR entangled states, homodyne detection, and linear optics and squeezing operations conditioned on measurement outcomes. This scheme may be used for fault-tolerant quantum computation in any optical scheme (qubit or continuous-variable). The teleportation of nondeterministic nonlinear gates employed in linear optics quantum computation is discussed.
