Quantum technology is the most relevant area of ​​modern physics, both applied and fundamental. Today, leading countries and private companies are attracting billions of investments in the development of quantum computing and quantum-protected communications. Among a number of possible implementations, quantum devices based on superconducting materials are considered the most promising - the largest computer companies, such as Google, IBM, Intel and others, build their versions of quantum computers based on superconducting qubits operating at ultra-low temperatures. And here one of the biggest problems of the world level is the control or elimination of quantum decoherence, which critically limits the efficiency of these computers. The aim of this project is to solve this important problem by implementing an algorithm of weak continuous quantum measurements of individual qubits and complex structures of selectively controlled qubits, which significantly reduces the relationship between the system of coherently connected qubits and the external environment. Techniques and equipment for quat thermalization will be developed taking into account the minimization of the local temperature of the control ports and the brightness temperature of cryogenic amplifiers, as well as new superconducting materials for the construction of qubits with improved parameters. Implementation of breakthrough measurement technology and involvement of young people in world-class quantum research are strategically important goals of the project.
