Emulation of the Fermi-Hubbard Model in One Dimension — •Jan-Michael Reiner, Michael Marthaler, and Gerd Schön — Institut für Theoretische Festkörperphysik, Karlsruhe Institute of Technology (KIT), 76131 Karlsruhe, Germany
For every qubit system which allows for σz and σx coupling between the qubits, it is possible to realize a Hamiltonian which is similar to the Fermi-Hubbard model in 1D. This way one can design a quantum emulator for this model.
We discuss a specific implementation of such an emulator for superconducting qubits. We consider tunable Transmon qubits, where the σz coupling is realized via inductive coupling and the σx coupling is realized via capacitive coupling. We then discuss the possible errors through disorder and how confidence in the emulation results can be established through measurements of local operators.
