Locality and Digital Quantum Simulation of Power-Law Interactions
The propagation of information in nonrelativistic quantum systems obeys a speed limit known as a Lieb-Robinson bound. We derive a new Lieb-Robinson bound for systems with interactions that decay with distance r as a power law, 1/r(α). The bound implies an effective light cone tighter than all previo...
