Quantum lower bounds for simulating fluid dynamics

The Takeaway
Despite long-standing hopes that quantum technology would revolutionize aerodynamics and weather forecasting, researchers proved that for common fluid equations, quantum computers face fundamental speed limits. In some scenarios, a quantum computer would actually take exponentially longer than a classical one to solve the same problem.
From the abstract
Developing quantum algorithms to simulate fluid dynamics has become an active area of research, as accelerating fluid simulations could have significant impact in both industry and fundamental science. While many approaches have been proposed for simulating fluid dynamics on quantum computers, it is largely unclear whether these algorithms will provide speedup over existing classical approaches. In this paper we give evidence that quantum computers cannot significantly outperform classical simul
