WHY INCLUDED

A quantum-computing theorist known for mathematical limits on quantum query algorithms and an openly available set of lecture notes spanning algorithms, communication and error correction.

CWIarXiv / Journal of the ACMarXiv

De Wolf helps define how quantum speedups should be assessed. His coauthored polynomial-method paper made it possible to prove important lower bounds on quantum queries, complementing the search for faster algorithms. His lecture notes provide a broad route into the field’s mathematical foundations. Together, the research and teaching emphasize precise models, stated assumptions and meaningful comparisons with classical computation, which are essential when evaluating ambitious claims about quantum advantage.

    Polynomial lower bounds for quantum queries

    With Robert Beals, Harry Buhrman, Richard Cleve and Michele Mosca, de Wolf developed a polynomial approach to proving quantum query lower bounds. The paper constrained possible quantum speedups for total Boolean functions and supplied a widely applicable analytical technique.

    Coauthor of the polynomial-method research with Beals, Buhrman, Cleve and Mosca.

    An open quantum-computing course

    De Wolf published his Quantum Computing: Lecture Notes on arXiv, drawing on a course first drafted in 2011 and subsequently updated. The notes cover algorithms, complexity, communication and error correction, making a substantial mathematical curriculum freely accessible.

    Author and continuing reviser of the openly published quantum-computing lecture notes.
