Tensor Network enhanced Dynamic Multiproduct Formulas

Understand

Tensor networks and quantum computation are two of the most powerful tools for the simulation of quantum many-body systems.

• Rather than viewing them as competing approaches, here we consider how these two methods can work in tandem.
• We introduce a novel algorithm that combines tensor networks and quantum computation to produce results that are more accurate than what could be achieved by either method used in isolation.
• Our algorithm is based on multiproduct formulas (MPF) - a technique that linearly combines Trotter product formulas to reduce algorithmic error.
