Compressible Navier--Stokes Flow in Schr\"odinger-Type Variables

James R. Beattie, Max Sokolova, Khush Negandhi, Bart Ripperda ยท 2026

Fluid equations are nonlinear, dissipative, and non-Hamiltonian, which makes their relation to Schr\"odinger evolution and quantum algorithms nontrivial. We derive an exact Eulerian Cole-Hopf-type refโ€ฆ
