> discovery of a new quantum algorithm that offers an exponential advantage for simulating coupled classical harmonic oscillators.
> To enable the simulation of a large number of coupled harmonic oscillators, we came up with a mapping that encodes the positions and velocities of all masses and springs into the quantum wavefunction of a system of qubits. Since the number of parameters describing the wavefunction of a system of qubits grows exponentially with the number of qubits, we can encode the information of N balls into a quantum mechanical system of only about log(N) qubits.

Consider a crypto currency pow that did that without the chunk counter. It'd be trivially exploitably by precalculating all the tree but the chunk that changed per nonce.
