Nonperturbative Gadget for Topological Quantum Codes
Nonperturbative Gadget for Topological Quantum Codes
Many-body entangled systems, in particular topologically ordered spin systems proposed as resources for quantum information processing tasks, often involve highly nonlocal interaction terms. While one may approximate such systems through two-body interactions perturbatively, these approaches have a number of drawbacks in practice. In this Letter, we propose a scheme to …
