SUMMARY:Mathematical Physics Seminar (309 VAN) - Robert Maxton\; University of Iowa
DESCRIPTION:Perturbative boundaries of quantum computing (cont.)\n\nRobert Maxton\; University of Iowa\n\nWe review the real-time evolution for lattice field theory. The zero radius of convergence of the corresponding perturbative series has motivated the development of a quantum computing algorithm for this problem (Jordan 2012). However\, we have shown that the digitization of the problem is an approximation that permits a finite radius of convergence of weak and strong coupling expansions. In this sequel to the October 2022 talk\, we discuss the implementation of \\phi^4 on quantum hardware and explore the singularity structure of the finite Hamiltonian\, particularly its potential for analytic continuation along the entire positive real axis.\n\n\nhttps://events.uiowa.edu/76543
