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
This position involves research into the computer-science aspects of quantum computing and quantum information theory. Specifically, the project will focus on one or more of the following topics: quantum algorithms and complexity, quantum machine learning, quantum communication, quantum cryptography. Depending on the most suitable topic, the research will be in collaboration with one or more of the following researchers: Jop Briët, Harry Buhrman, Peter Grünwald, Stacey Jeffery, Maris Ozols, Christian Schaffner, Michael Walter, and Ronald de Wolf. The position is on the NWO-funded QuantERA project QuantAlgo, for one or two years, and can start at any time after 1 August 2018.
