Buhrman develops the mathematical foundations of quantum algorithms and communication, and has built research programs that connect those ideas with quantum-software and industrial computing efforts.
QuantinuumarXivCentrum Wiskunde & InformaticaBuhrman combines foundational computer science with institution-building. His quantum-fingerprinting work demonstrated a sharply defined communication advantage: small quantum messages can distinguish long strings under a model where comparable classical messages face a stronger constraint. He later co-founded QuSoft to concentrate research on quantum software and now leads algorithms and innovation as a chief scientist at Quantinuum. The connection is the translation of what quantum information makes possible into algorithms and research capacity. His current identification follows the documented move from CWI, rather than carrying forward an outdated full-time institutional role.

Quantum fingerprints for communication
Buhrman, Richard Cleve, John Watrous and Ronald de Wolf showed that quantum fingerprints can be exponentially shorter than the original strings without shared randomness or entanglement between senders. The result establishes a quantum–classical separation in the simultaneous-message model, not a general compression scheme for recovering all original data.

Cofounding QuSoft
Buhrman co-founded QuSoft with Kareljan Schoutens, helping establish an institute centered on the software and theoretical side of quantum computing. CWI’s later account connects this work with his long-running quantum-research program and subsequent move into industrial algorithm development.
QuSoft was cofounded by Harry Buhrman and Kareljan Schoutens, as documented by CWI.

Moving algorithm development into industry
Quantinuum appointed Buhrman chief scientist for algorithms and innovation in December 2023. CWI’s 2026 farewell account confirms the move, while noting a continuing part-time professorship at the University of Amsterdam.
Quantinuum’s appointment of Harry Buhrman is corroborated by CWI’s later institutional account.
