FermiQP is a demonstrator experiment for a lattice based fermionic quantum processor with neutral Li-6 atoms. The experiment aims to combine the versatility of digital quantum gates with the power of analogue Fermi-Hubbard simulators. Single qubit gates will be implemented as Raman rotations between hyperfine states, while controlled collisions between atoms in a bichromatic lattice will constitute two-qubit gates. Tweezer-based resorting techniques will enable all-to-all connectivity of the qubits. This also allows robust control of the starting configuration for investigating the Fermi-Hubbard phase diagram. We present the status of the experiment, including progress on the implementation of single qubit addressing, single-site and spin resolved quantum gas microscopy, and new cooling schemes for fast degenerate Fermi gas preparation.
