Factoring a 300-digit number would require stringing together thousands of gates, and even quantum computing's most enthusiastic supporters admit that such a goal is exceedingly daunting.1997 February 18, George Johnson, “Quantum Theorists Trying to Surpass Digital Computing”, in The New York Times, →ISSN:
