With the development of quantum chips, quantum communication is becoming essential for quantum computing and quantum networks. Flying Qubits, quantum information carried by photons, play a vital role in transferring data between nodes. Prof. Guofeng ZHANG, Professor of Department of Applied Mathematics of The Hong Kong Polytechnic University is dedicated to developing precise control methods for flying qubits, aiming to significantly improve the reliability and fidelity of quantum information transfer in future technologies.

By imaging the superfluid density and superconducting transition temperature in an infinite-layer superconductor, researchers revealed a strong correlation between the two quantities. This correlation is quantitatively similar to that reported in cuprate superconductors, hinting at a close connection between the superconductivity of infinite-layer nickelates and that of cuprates.
