报告题目:Model Checking for Verification of Quantum Circuits
摘要: In this talk, I will describe a framework for assertion-based verification of quantum circuits by applying model checking techniques for quantum systems developed in our previous work, in which:
(1) noiseless and noisy quantum circuits are modelled as quantum automata and quantum Markov chains, respectively, and they are further represented by tensor networks;
(2) Quantum assertions are specified by a temporal extension of Birkhoff-von Neumann quantum logic;
(3) Algorithms for reachability analysis and model checking of quantum circuits are developed based on contraction of tensor networks.

报告题目:Some Recent Advances in Quantum Artificial Intelligence
摘要: Quantum artificial intelligence (Quantum AI) is an emergent interdisciplinary field that explores the interplay between artificial intelligence and quantum physics. On the one hand, judiciously designed quantum algorithms may exhibit exponential advantages in solving certain AI problems; on the other hand, ideas and techniques from AI can also be exploited to tackle challenging problems in the quantum domain. In this talk, I will first make a brief introduction to this field and review some recent progresses. I will talk about several concrete examples to illustrate how AI and quantum physics can promote studies in both fields. At the end of the talk, I will pose some fundamental challenges facing quantum AI that, if overcome, would give a significant boost to this fledgling field full of uncertainties and opportunities.
