    I really hate it when people come up with the simple "Quantum computer 1000 times faster than conventional computer". It's not just overly simplistic, it's wrong.

    Quantum computers can turn some problems that require exponential time to solve into a polynomial time. So instead of taking 2^n time, it might take n^3 time. That's cannot in any realistic way be described as being "X times faster".

    I'm not buying your attempt to downplay this because of how the media has portrayed this event. It's obvious to anyone with a calculator and wikipedia that this is a big deal, and not a minor event. Using the low estimates of 200,000 gallons/day, and "early next week" being Tuesday perhaps, that's 20 days at 200,000 gallons/day for a total of 4 million gallons of oil.
