- Abstract summary: We propose an efficient scheme to generate and characterize global entanglement in the optical lattice.
With only two-layer quantum circuits, the generation utilizes two-qubit entangling gates based on the superexchange interaction in double wells.
Our entanglement generation and verification protocols provide the foundation for the further quantum information processing in optical lattice.

- Abstract: To achieve scalable quantum information processing, great efforts have been
devoted to the creation of large-scale entangled states in various physical
systems. Ultracold atom in optical lattice is considered as one of the
promising platforms due to its feasible initialization and parallel
manipulation. In this work, we propose an efficient scheme to generate and
characterize global entanglement in the optical lattice. With only two-layer
quantum circuits, the generation utilizes two-qubit entangling gates based on
the superexchange interaction in double wells. The parallelism of these
operations enables the generation to be fast and scalable. To verify the
entanglement of this non-stabilizer state, we mainly design three complementary
detection protocols which are less resource-consuming compared to the full
tomography. In particular, one just needs two homogenous local measurement
settings to identify the entanglement property. Our entanglement generation and
verification protocols provide the foundation for the further quantum
information processing in optical lattice.
