• Abstract: The Hamiltonian approach can be used successfully to study the real-time evolution of a non-Abelian lattice gauge theory on the available noisy quantum computers. In this work, results from the real-time evolution of SU(2) pure gauge theory on IBM hardware are presented. The long real-time evolution spanning dozens of Trotter steps with hundreds of CNOT gates and the observation of a traveling excitation on the lattice were made possible by using a collection of error mitigation techniques. Self-mitigation is our novel tool, which consists of using the same physics circuit as a noise-mitigation circuit.

• Quantum simulation of lattice gauge theories via deterministic duality transformations assisted by measurements [0.0]
  lattice gauge theories are likely limited due to the violation of the Gauss law constraint and the complexity of the real-time dynamics. We propose to simulate dynamics of lattice gauge theories by using the Kramers-Wannier transfomation via cluster-state-like entanglers. We give explicit examples with the low dimensional pure gauge theories and gauge theories coupled to bosonic/fermionic matters.

  variational quantum time evolution is a promising candidate for near-term devices. We show that our algorithm accurately reproduces the system dynamics at a fraction of the cost of standard variational quantum time evolution algorithms. As an application of quantum imaginary-time evolution, we calculate a thermodynamic observable, the energy per site, of the Heisenberg model.
