Although numerous quantum algorithms for solving partial differential equations have been proposed, the reconstruction of solutions (i.e., the readout of quantum states) remains a crucial problem. In this work, we first propose and compare several efficient readout methods in real and Fourier space. Next, we apply the methods for benchmark solutions in computational fluid dynamics (CFD) and demonstrate great improvements compared to the conventional method for large grid numbers.
