Harry Buhrman (born 1966) is a Dutch computer scientist, currently professor of algorithms, complexity theory, and quantum computing at the University of Amsterdam (UvA). He is a co-founder of QuSoft, the Dutch research center for quantum software. He works at Quantinuum in the UK.

Buhrman’s research interests are in quantum computing, quantum information, quantum cryptography, computational complexity theory, Kolmogorov complexity, and computational biology.

Buhrman contributed substantially to the quantum analogue of communication complexity, exhibiting an advantage of the use of qubits in distributed information-processing tasks. Although quantum entanglement cannot be used to replace communication, it can be used to reduce the communication exponentially.
