Quantum factorization of 56153 with only 4 qubits
... et al. [1] in 2012 factored an entire class of numbers, and not just the one number that they reported (which was 143). The largest such number that we found without using any prior knowledge of the solution to the factorization problem was 56153. Since the experiment in [1] only involved 4 qubits, ...
