Cited from quantum phase estimation for the overlap hypothesis and for the passage from a unitary eigenvalue to the eigenvalues of a Hamiltonian. The abstract's 50-to-100-qubit remark is their estimate for certain atomic problems. It is not a general qubit count. The arXiv preprint is quant-ph/9807070; the journal version is Physical Review Letters (1999).
