The FMN Laboratory team is assembling the cryogenic part of the quantum computer, which provides cooling of superconducting processors to almost absolute zero (-273.1°C). The chips of such processors are based on superconducting qubits and coplanar resonators operating at microwave frequencies. The qubit (“quantum bit”) – the driving force of a quantum computer – exhibits its unique properties only in conditions of absolute zero temperature and complete protection against external influences provided by the dilution cryostat. The scheme and construction of a measurement circuit, which includes hundreds of elements (control devices, special filters, and screens, attenuators, microwave components, etc.), largely influence the quality of the quantum systems we create.
