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.

The week of quantum computing

The week of quantum computing

Starting 12 January 2015, the Universiteit van Nederland publishes five public lectures by Harry Buhrman, head of the research group quantum computing at CWI. The series of lectures features the do's and don'ts of the computer of the future. From Monday through Friday, a new lecture will be available on the site of the Universiteit van Nederland each day.
