EA.00001: Advances in quantum simulation for nuclear physics Invited Speaker: Zohreh Davoudi A vigorous program has formed in recent years in various scientific disciplines to take advantage of near-term and future quantum-simulation and quantum-computing hardware to study complex quantum many-body systems, building upon the vision of Richard Feynman for quantum simulation. Such activities have started in nuclear physics recently, hoping to bring new and powerful experimental and computational tools to address a range of challenging problems in strongly interacting nuclear many-body systems. In this talk, I review a number of important developments, including proposals for simulating strongly interacting field theories with the goal of studying strong dynamics of quarks and gluons in the heart of matter, and for quantum computations of hadron and nuclear structure. The hardware technologies that are expected to enable both the analog simulations and the digital quantum computations of these problems will be enumerated, and their unique feature for applications in nuclear physics will be outlined.

EA.00002: Experimental techniques for quantum simulation and computation using trapped ions Invited Speaker: Crystal Senko Quantum technologies, such as trapped atomic ions, have advanced to the point of carrying out proof-of-principle demonstrations of quantum computing and quantum simulation. A current focus of interest is exploring how quantum simulation tools can be exploited for nuclear physics related problems, such as the simulation of lattice gauge theories. This talk will present a broad overview of trapped ion quantum simulation experiments, describing the tools and techniques that have been demonstrated in a laboratory setting, and the current challenges in extending these results to more complex systems. Trapped ions are well suited for both ``digital'' quantum simulations, in which quantum logic gates are used to construct a unitary operator of interest, as well as ``analog'' simulations, in which the trapped ions are induced to obey dynamics analogous to a quantum system of interest, such as a spin chain. I will review existing protocols for using trapped ions to simulate spin-like and boson-like degrees of freedom and to control their interactions, as well as giving an outlook on near-term efforts to expand the capabilities of such experiments.

EA.00003: Nuclear dynamics on current generation quantum devices Invited Speaker: Alessandro Roggero Studying the real-time dynamics of strongly correlated many-particle systems is one of the most promising applications of future fault-tolerant quantum computers. The current generation of quantum devices are however still too small and noisy to compete with classical calculations. In this talk I will present recent simulations carried on today's quantum devices of the time-dependent response in a very simple model for the triton, and discuss some of the challenges we face in fighting against the noise.
