I believe I may have mentioned at some point in the history of this blog, or its precursor, that at least one great physicist, Roger Penrose, believes quantum mechanics offers the key to the understanding of how consciousness arises within the function of the human brain. Today, I simply want to make the observation that quantum computing is no longer a hypothesis. It is a fact. Google declared its breakthrough this year. Some of the premier quantitative-analytic hedge funds in the world, including Renaissance and DE Shaw, have high hopes for quantum computing and expect that it will help them discover and make profitable use of now-invisible patterns in the markets. Let us be clear on what Google is saying. It says it has physical operating computers that make use of the quantum aspects of matter to outperform conventional (digital) computers for some specific tasks, a situation it grandly calls quantum supremacy. The qualifying phrase there, "some specific tasks,"...
