Controlled quantum teleportation might one day become a building block for future quantum Internet. Its first implementation on quantum bits has recently been reported by scientists from the Joint laboratory of Optics of Palacky University and Institute of Physics of the Czech Academy of Sciences. Using this idea, one can significantly increase the quantum data flow in multi-user networks and even across large distances.
In the area of quantum and nonlinear optics, mainly the topics related to generation, transmission, detection, and quantum processing of information are treated, using the fields of photon pairs obtained by parametric downconversion as the main tool.
