Optical quantum computation requires the ability to switch quantum optical paths, but classical devices fall short of meeting key requirements such as low optical loss and high repetition rate. We propose a novel methodology based on quantum teleportation (QT), for which a demonstration experiment is currently underway. This presentation reports on experimental results of selective QT using squeezed states as inputs. The squeezed states serve as resources for quantum computation, and their non-classicality was preserved and observable in the output states.
