Single photons are one of the most convenient systems for performing quantum experiments, since they do not require special external conditions as opposite to single atoms and ions or solid state systems. Despite the fact that single photons do not interact with each other in a linear approximation, multi-qubit transformations can be implemented quite efficiently. This laboratory investigates the problems associated with creation of an integrated optical platform for a linear optical quantum computer. Also the laboratory solves theoretical and computational problems associated with the design of individual quantum gates and medium- to large-scale linear optical systems.
