Solving nuclear many-body problems from first principles is widely recognized as a computationally hard problem. This is especially true for reactions where one employs ab initio information on nuclear structure. For classical computers, this requires computational resources that scale exponentially with the number of neutrons and protons and with the basis spaces required for converged results. Hence, classical calculations rapidly become intractable even with world-leading supercomputers. Quantum computing techniques offer a promise to circumvent the roadblock of the exponential scaling and future quantum computers are expected to become powerful tools for solving complex nuclear structure and reaction problems. In this talk, I will show basics of quantum computing techniques. I will also present our proof-of-principle quantum algorithm for nuclear elastic and inelastic scattering with ab initio nuclear structure results as input. A future goal is to extend quantum computing to solve both the structure and the reactions. Online Tencent/VOOV meeting: https://meeting.tencent.com/s/KBhtFS9e5zxn ID: 549 391 364
