  1. DMCA vs Quantum computers by roman_mir · · Score: 3, Interesting

    I wonder if DMCA would render building, selling and using such machines illegal, since quantum computers can be used to compute securitykeys for any encryption algorithms in a feasible amount of time?

    The Economist had a good article back in May about the state of the art (7 qubits), and some of the practical difficilties facing quantum computing.

    "Dr Cory says that the program for factorising large numbers [400 digits] will require about 1,000 qubits simply to store the problem. But each of these qubits will require dozens of extra qubits for error-checking. That means that a useful computer will need tens of thousands of qubits to come up with a reliable answer. At seven and counting, that goal is a long way off. "
