Description
We introduce a novel quantum computational framework for simulating lattice gauge theories by leveraging the advantages of both discrete (qubit) and continuous variables (qumode) quantum computing. The simulations of these hybrid systems can be realized with various quantum hardware platforms like trapped-ion and photonic systems.
By explicitly solving Gauss’s Law at each vertex of the two-dimensional spacial lattice, we construct the QED Hamiltonian for an $N\times N$ plaquette system, retaining only the relevant dynamical degrees of freedom. We then present several hybrid formulations in which the bosonic and fermionic fields are encoded in qumodes and qubits, respectively. To validate our approach, we benchmark the framework by simulating the one-plaquette system - both with and without fermions - and comparing the results to known analytical solutions.
