The QUANTUM CONFINED INTENSE LIGHT LABORATORY was created at the Federal State Budget Research Institution "Federal Research Center Institute of Applied Physics of the Russian Academy of Sciences" (IAP RAS) with the support of the "megagrants" program and conducts research into the creation of extremely localized electromagnetic fields and the study of classical and quantum effects in the interaction of matter and quantum vacuum with such structures, and the development of devices of devices for quantum information technologies that use a strong localization of the field. The study of quantum effects in the interaction of high-intensity ultrashort laser radiation with matter, including interaction with quantum vacuum, as well as the generation of non-classical light states, is one of the most rapidly developing directions of quantum and nonlinear optics. Of particular interest are extremely localized structures of the electromagnetic field, which, on the one hand, make it possible to multiply the peak intensity many times, and, on the other hand, to study the interaction with nanoscale objects. Limit localization implies focusing in space and a time limit due to the use of femtosecond pulses. The goal of the activity, which is planned to be conducted in the newly created laboratory, is the development of new methods for creating extremely localized structures of electromagnetic fields and the study of classical and quantum effects in the interaction of matter and quantum vacuum with such structures, as well as the development of elements of devices for quantum information technologies that use strong localization of the field.
