Given that this is a business primer - a good one! - and not a rigorous technical one - but few corrections.
First, superconductors do not require absolute zero, for tin - 3.7 Kelvins, lead - 7.2. Liquid helium is at 4.2 Kelvins and is used to get metals go to superconducting state. Temperatures as close to absolute zero as possible needed to isolate qubits from external interactions but not to create superconducting effect.
More serious statement though - QC applications. The main challenge comes from the fact that while QC operates on millions or billions numbers simultaneously, the final result of the computation is a single number - collapsing all those qubit states. Shor’s genius was in finding an algorithm where this number would be useful - in finding large primes. There is a handful of applications (Grover’s search) that benefit from QC nature but to claim that there are multiple QC algorithms is misleading and is expected on a grant proposal 🤘
