You can use the weird physics of particles walking through walls to "tunnel" straight to the answers of impossible math problems.

Why it matters
Standard optimization algorithms often get stuck in 'local minima,' similar to a hiker trapped in a small valley. By reframing these math problems using the Schroedinger equation, researchers showed that 'quantum tunneling' can be used to pass through these barriers and guarantee that the algorithm finds the absolute best possible answer.
From the abstract
This work presents a quantum mechanical framework for analyzing quantization-based optimization algorithms. The sampling process of the quantization-based search is modeled as a gradient-flow dissipative system, leading to a Hamilton-Jacobi-Bellman (HJB) representation. Through a suitable transformation of the objective function, this formulation yields the Schroedinger equation, which reveals that quantum tunneling enables escape from local minima and guarantees access to the global optimum.
