Information propagation in long-range quantum many-body systems

The authors study the information transportation capabilities of bosonic quantum many-body systems with long-range interactions. They rigorously prove that initially localized quantum states exhibit a linear Lieb-Robinson light cone for information propagation and they derive consequences of this result, e.g., bounds on quantum messaging and quantum state control.
