SUMMARY:Quantum computing simulation of a mixed spin-boson Hamiltonian and
  its   performance for a cavity quantum electrodynamics problem - Maria Tu

DESCRIPTION:We aim to explore the potential of quantum computers for solvi
 ng real-world quantum problems. In particular\, we are interested in exami
 ning the multi-photon effects of cavity quantum electrodynamics (QED). Her
 e\, we present a method to simulate a phase transition in coupled cavities
  allowing photon hopping. We map spin and boson excitations to different p
 arts of the qubit register and introduce a boson-to-qubit mapping that sim
 plifies multiphoton-multiatom studies\, employing the inverse Holstein-Pri
 makoff transformation. The time evolution is studied using first-order Tro
 tterization. We replicate classical simulation results of the phase transi
 tion with a noiseless six-qubit simulation.\n\n\nThe talk is based on this
