A first-person teaching case study reports that a project-based HHL-for-CT-imaging assignment helped the authors learn quantum computing, without measured learning outcomes, and confirms HHL is impractical for real CT today.

abstract
We reiterate the contribution made by Harrow, Hassidim, and Llyod to the quantum matrix equation solver with the emphasis on the algorithm description and the error analysis derivation details. Moreover, the behavior of the amplitudes of the phase register on the completion of the Quantum Phase Estimation is studied. This study is beneficial for the comprehension of the choice of the phase register size and its interrelation with the Hamiltonian simulation duration in the algorithm setup phase.
