During the on-site visit to the laboratory, the students were led by volunteers. We have visited the Spiritual Loop Laboratory, the Medical Imaging Center, the Intelligent Detection and Imaging Laboratory,

the Knowledge Surface Access and Intelligent Information Technology Laboratory, the Intelligent Multimedia Content Computing Laboratory, the Wireless Optical Communication and Network Research Center, the Intelligent Network System and the Future Network Infrastructure Laboratory, and the Medical Imaging Center - Magnetic Resonance System Laboratory.

During the visit, the teachers combined their own research results to bring students a high-quality scientific enlightenment lesson, which opened up the students' thinking and vision.

The senior students explained the advanced equipment of the laboratory in detail, showed the charm of scientific experiments to the students, and combined with their own learning and research experience,

gave specific suggestions on how to start the road of scientific research. The students listened carefully to the explanations of the laboratory teachers and seniors, actively asked questions, and greatly deepened their knowledge and understanding of scientific experiments.

Senior students from the Light Wave Laboratory, Data Science Laboratory and Intelligence Perception and Information Processing Laboratory conducted online lectures on the research fields of the laboratory,

introduced the major scientific research achievements of the laboratory, and encouraged the students to participate in scientific research work as soon as possible. In the questioning session,

the students asked the guest speakers questions about the issues they were interested in, and the seniors responded with humorous answers, which not only solved the doubts of the students, but also gave the students new inspiration.

"Into the Lab" activities to guide students to clear the direction of interest and understand the relevant scientific research innovation results as the goal, with a variety of activities to provide students with a close understanding of the frontier of science and technology,

explore scientific research secrets and exchange innovative ideas platform. Through this activity, the students experienced the beauty of information technology, strengthened academic exchanges,

and laid a solid foundation for cultivating a good scientific research atmosphere.The University of Science and Technology of China has successfully overcome ambient noise in quantum teleportation

The team of academician Guo Guangcan of the University of Science and Technology of China has made important progress in quantum teleportation research. The team, including Li Chuanfeng and Liu Zhao Di,

worked with the theoretical research group of the University of Turku in Finland to successfully overcome the environmental noise by using multi-body hybrid entanglement and achieve high-fidelity quantum teleportation.

Quantum teleportation is an important protocol of quantum communication, which can transmit unknown quantum states remotely through quantum entanglement. Since quantum entanglement is very fragile, quantum teleportation is easily affected by noise. How to realize high-fidelity quantum teleportation in noisy environment is an urgent problem to be solved.

Previously, in order to solve the decoherence problem of open quantum systems in noisy environments, the research team developed a set of methods for complete regulation of photon polarization and frequency based on clever optical path design and programmable spatial light modulator,

so as to achieve a fully controllable phase decoherence quantum simulator, and realize quantum teleportation based on non-local memory effects to overcome noise. However, non-local memory effects require a more demanding quantum resource, such as environmental entanglement, which cannot be satisfied under normal circumstances.

Based on the above results, in this work, the research team designed and realized a more universal quantum teleportation to overcome environmental noise.

The research team first demonstrated that phase decoherence in the evolution of open quantum systems can be completely reversed by performing specific phase modulation to the environment of a single quantum system,

and that the method can be generalized to any multi-body system. Then, the polarization of the photon is taken as the quantum system, and the frequency of the photon is taken as the noise environment.

Based on a fully controllable phase decoherence quantum simulator, a specific phase modulation is loaded in the environment to prepare the initial state of two-photon polarimetric frequency-mixed entanglement, and then the two photons are distributed to Alice and Bob. Decoherence evolution is performed at the Alice end,

and then the Bell measurement is made with the quantum state to be transferred, and then decoherence evolution is performed at the Bob end. Finally, the corresponding unitary operation is performed on the obtained qubit through classical communication, and the transmitted quantum state is obtained,

and the measured fidelity is close to 90%. Since the polarization state of the two photons in this process never violates the Bell inequality, the experiment realizes quantum teleportation based on hidden quantum nonlocality.
