Long-range entangled states are of fundamental interest in condensed matter physics as they are central to the study of major sub-fields, such as topological order and quantum criticality, as well as applications involving quantum error correcting codes and quantum metrology.

This DOE Basic Energy Sciences project is exploring recent ideas that center on designing efficient quantum circuits to generate general classes of states with long-range entanglement. This includes understanding the role of resources such as non-unitary and non-local operations to design efficient state-preparation algorithms that can be implemented on future large-scale quantum devices, as well as designing efficient protocols to probe properties, e.g., the entanglement structure of these states, with high fidelity.
