报告摘要：Recently, there has been an increasing interest in a new classification of nonlinear dynamical systems, including two kinds of attractors: self-excited attractors and hidden attractors. Self-excited attractors can be localized straightforwardly by applying a standard computational procedure. In contrast, in systems with hidden attractors we have to develop a specific computational procedure to identify the hidden attractors because the equilibrium points do not help their localization. Especially systems with hidden attractors could play a vital role in the design of new advanced chaotic cryptosystems.
On the other hand, quantum computation is a rapidly growing field, and many breakthroughs have been achieved during the past decades. Quantum computation is transitioning from an emerging branch of science into a mature research field in science and engineering. Quantum walks, the quantum mechanical counterpart of classical random walks is an advanced tool for building quantum algorithms that have been recently shown to constitute a universal model of quantum computation. Additionally, quantum walks may be employed to develop quantum cryptography protocols as well as quantum networks. Quantum walks is now a solid field of quantum computation research full of exciting open problems for physicists, computer scientists and engineers.
Furthermore, nowadays, cybersecurity, which is the practice of protecting systems, networks, and programs from digital attacks, is becoming more prevalent. Cyberattacks are usually aimed at accessing, changing, or destroying sensitive information, extorting money from users, or interrupting normal business processes. Therefore, implementing effective cybersecurity measures is particularly challenging today because there are more devices than people, while the attackers are becoming more innovative.
