Description
Leader of the group Algorithms and Complexity: Harry Buhrman.
Our research group designs software for the computing technology of the future, especially quantum computing. Based on the laws of quantum mechanics, which tell us that systems and particles can be in multiple states at once, quantum computing is radically different from computing as we know it. Our quantum software requires fundamentally different techniques and approaches based on superposition, interference and entanglement. Ultimately, our research will result in better, faster and more reliable computer systems for society. Our research group is involved in QuSoft, the new Dutch research centre for quantum software.
Vacancies
Postdoc / Postdoctoral Researcher on the subject of the computer-science aspects of quantum computing and quantum information theory

Cum laude for PhD thesis on advancing theory of lower bounds for multiplying matrices faster
Jeroen Zuiddam (CWI) developed new mathematical instruments to study the problem of multiplying large matrices fast. He defends his PhD thesis ‘Algebraic complexity, asymptotic spectra and entanglement polytopes’ at the UvA on 23 October. He received a 'cum laude' predicate.
Arunachalam presents findings on quantum algorithms and machine learning
On 25 April 2018, CWI PhD student Srinivasan Arunachalam will defend his thesis at the University of Amsterdam. In his thesis, Arunachalam analyzes the strengths and weaknesses of the quantum computer for a number of problems.
European researchers publish Quantum Software Manifesto
Researchers and industry specialists across Europe, led by Harry Buhrman (director of QuSoft, group leader at CWI, and professor at the University of Amsterdam), have launched a Quantum Software Manifesto. With the Manifesto, the group aims to increase awareness of and support for quantum software research.
Quantum revolution at Lowlands
Quantum experts Harry Buhrman (CWI, QuSoft and UvA) and Ronald Hanson (QuTech, TU Delft) showed a glimpse of their scientific minds at the Lowlands pop festival 2017, discussing the quantum revolution.
