Digital Quantum Computing (QC) based on Quantum Entanglement (QE) promises exponentially massive parallelism with modest hardware resources.  Such a fantastic claim should be subject to especially strong verification, but this has not been the case.  QE was introduced early in the history of quantum mechanics (with key roles on both sides played by Pauli, Von Neumann, Einstein, and Schrodinger), and is widely accepted despite never having been fully verified.  I would suggest that QE is a non-physical mathematical artifact, and that key experiments need to be done before proceeding on QC.  On the other hand, analog QC such as quantum annealing does not seem to depend on QE, and may provide significant benefits for certain niche applications.
