Name of the project:

Engineering of states of light for quantum computations and sensoric

Goals of project:

Generating new knowledge, creating world-class infrastructure and obtaining new results in the field of quantum information technologies on the basis of this infrastructure in collaboration with leading research centers of Russia and foreign countries;
Opening a master’‎s degree program “Quantum optical technologies”, within which we are planning to develop educational courses for bachelor’‎s and master’‎s degree students of the South Ural State University in the domains of modern quantum technologies and quantum metrology, including the creation of a research and education complex for conducting work in quantum optics and quantum informatics;
Training world-class specialists in the field of quantum technologies and quantum computations, primarily for the needs of the economy of the Chelyabinsk region;
Dissemination of knowledge, commercialization of fundamental results produced during the implementation of the project;
Organizing international seminars, schools for young researchers, conferences in the domain of modern quantum technologies with the engagement of leading Russian and foreign scientists.

Project objective:

Researching hybrid quantum states of light in problems of quantum data processing;
Developing algorithms and protocols based on quantum states of light for quantum lossless computation operations;
Modeling and experimentally implementing optimal quantum-optical schemes with non-Gaussian states of light in the field of quantum computations and metrology.

Research directions: Physics and astronomy

Planned project results:

A theory of the generation of continuous states observed with definite parity produced from a single-mode compressed vacuum state, which includes analytical expressions of these states, their static characteristics, including the mean number of photons, the degree of compression and the mean derivation of the number of photons.
In the experiment we will implement states of this family for the case of the detachment of some number of photons. We will study the characteristics of the generated states.
We will create a useful model describing a protocol for generating Schrödinger's cats (SC) with wide amplitudes (with a mean number of particles of up to 25) with the maximum attainable precision (0.99 and higher) and the rate of generation accounting for the imperfections of the experimental measurement equipment.
Researching the possibility of achieving such states in an experiment, which will become a basis for the creation of generators of odd/even SC states in quantum metrology at the level of the Heisenberg limit.
An algorithm for generating hybrid clusters states, consisting of HH states of defined parity and photonic states. Some of the hybrid cluster states will be implemented experimentally and adapted for computational problems.
New schemes and protocols for quantum computations on an optical chip with the use of nonclassical states of light that will be relatively prone to losses.
New schemes and protocols for implementing distributed quantum sensorics systems with the measurement (assessment) of phases at an accuracy level defined by the Hesenberg limit.
Patented experimental samples of photonic quantum simulators on a chip performing a basic set of operations with photonic qubits.
Training highly qualified professionals that will work in the domain of quantum technologies.
Knowledge accumulated in the course of the implementation of the project will be incorporated into quantum optics and quantum informatics education courses for undergraduate and postgraduate students of the South Ural State University. The results will also be used in additional training programs.
Some of the problems reviewed in the project will form a basis of master’‎s and candidate of science degree dissertations of employees of the Laboratory.
Creating a research and education complex on the grounds of the South Ural State University to perform laboratory case studies in quantum optics and quantum informatics that will include a number of automated experimental benches including software needed for case studies as well as a complete set of guidance materials.
