Quantum State Engineering of a Hubbard System with Ultracold Fermions

Quantum State Engineering of a Hubbard System with Ultracold Fermions

Accessing new regimes in quantum simulation requires the development of new techniques for quantum state preparation. We demonstrate the quantum state engineering of a strongly correlated many-body state of the two-component repulsive Fermi-Hubbard model on a square lattice. Our scheme makes use of an ultralow entropy doublon band insulator created …
