This is confusing to me as I thought the simple act of measuring the wave collapsed the wavefunction.

The arxiv has more details. They sparsely populated a dense lattice with particles. Then they turned off the lattice, which allowed all the particles’ wave functions to evolve according to the Schrödinger equation. Then they turned the lattice back on, which constitutes a measurement and collapses the wave functions. Then they took statistics on how far and in which direction each particle traveled and compared those statistics to the ones implied by Schrödinger’s equation.

So is this really just a different version of the double-slit experiment, building up a statistical measurement of the waveform by performing many discrete measurements?

Indeed, the article is extremely confusing. The wave in wave-particle duality is not the wave (function), one that collapses. For instance, electromagnetic wave is not the same thing as the wave function of the photon.
