Description
Quantum computing for lattice gauge theories (LGT) has drawn rapidly growing interest from a variety of physics communities, which has the potential of overcoming sign problems in Euclidean lattice approach and is suitable for real-time nonperturbative simulation. In this talk, I will review the Kogut-Susskind Hamiltonian for LGT in the electric basis and some studies of performing quantum simulations for pure SU(2) LGT on hardware. Then I will discuss a field basis for lattice QED in the Coulomb gauge, using which I can prove bounds for qubit and gate costs rigorously. Finally, I will explain two error correction codes that are constructed by converting Gauss's law constraints into stabilizers for the minimally truncated SU(2) LGT.
