Optical lattices have become a widely used tool to study and simulate several models of condensed matter physics. In quantum information they have shown to deliver a promising resource for quantum computers and quantum simulators. Especially the Mott-Insulator phase of bosons described by the Bose-Hubbard model creates the basis of a scalable quantum computer.
In order to realise this phase in the experiment
Two-dimensional Mott-Insulators can be optimised using experimental output instead of the DMRG simulation. This output gets processed in a closed-loop setup by updating the guess ramp every time one loop cycle has finished.
Because of the close relation of this work to applications in lattice experiments we work closely with experimentalists realising optical lattices with bosons in 1D and 2D.
