    Extractions: Presently I study quantum algorithms. Previously I have worked on condensed matter experiment and simulation. It is now believed that quantum computers can solve certain problems more efficiently than classical computers. For example, quantum algorithms have been discovered which can factor large numbers in an amount of time which varies roughly as the cube of the number of digits. No classical algorithm with such efficiency is known and many people suspect that it is mathematically impossible for one to exist, although no one has yet succeeded in proving this. Quantum algorithms superior to all known classical algorithms have been discovered for several problems, and in a small number of cases, the superiority of quantum techniques has been rigorously proven. However, the full power of quantum computers relative to classical computers is still largely unknown, and the search for new quantum algorithms remains active. My own research has so far involved quantum numerical algorithms. Specifically, I found that it is possible to perform numerical gradient estimation in any number of dimensions using two function evaluations, whereas classically the required number of function evaluations scales linearly with the dimensionality. I completed this research at MIT, where I have been enjoying the advice and insights of

    Extractions: Site search: Welcome to my selection of mathematical puzzles. I aim to add one new puzzle each week, so please stop by again. What's new? See puzzles 78 through 80 , and puzzle 81 onward The puzzles presented here are selected for the deceptive simplicity of their statement, or the elegance of their solution. They range over geometry, probability, number theory, algebra, calculus, and logic. All require a certain ingenuity, but usually only pre-college math. Some puzzles are original. Explaining how an answer is arrived at is more important than the answer itself. To this end, hints, answers, and fully worked solutions are provided, together with links to relevant mathematical topics. Further references are provided with many of the solutions. The puzzles are intended to be fun, with an educational element. Some of these puzzles I first encountered on Clifford Pickover's Yahoo! Group , host to fascinating discussions on mathematics, science, art, religion, philosophy, and the extraordinary. Where this is the case, I provide a link in the credit, which is at the bottom of the solution page. (However, since the group's messages are accessible to members only, you would need to join the group in order to follow the link.) I usually provide only a proximate credit; some puzzles have been around for so long it can be difficult to trace their provenance. I welcome feedback of any kind. Should you find a puzzle ambiguous, a hint misleading, an answer incorrect, or a solution unclear, please let me know. I also welcome
