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.

New protocols can speed up early quantum computers
How can quantum computers perform as many computations as possible within the short lifespan of quantum memory? CWI researcher Koen Groenland developed methods to do so. His results can help improve early quantum computers.
NWO KLEIN grant for Stacey Jeffery and Marie Colette van Lieshout
CWI researchers Stacey Jeffery and Marie Colette van Lieshout have been awarded a grant from the NWO KLEIN programme.
ERCIM Cor Baayen Young Researcher Award 2019 for András Gilyén and Ninon Burgos
András Gilyén has been selected as winner of the 2019 ERCIM Cor Baayen Young Researcher Award, together with CNRS researcher Ninon Burgos. The award committee lauds their outstanding scientific research quality and its impact on science. Gilyén performed his award winning PhD research at CWI.
Mathematical tools reconstruct ancient genetic code
The genetic code of the last universal common ancestor of all present life on earth, appears to be surprisingly advanced. In his PhD thesis, Peter van der Gulik provides mathematical tools to reconstruct this genetic code. He also proposes a new parameter to characterize the genetic code that provides information about the production of amino acids.

4th QSC General Assembly
Start: 2020-06-12 14:00:00+02:00 End: 2020-06-12 17:30:00+02:00
Everyone is welcome to attend the 4th General Assembly of the Quantum Software Consortium (QSC). This Quantum program is part of the Networks Scientific Conference; all information can be found on the website. This track is about network phenomena in quantum information science, a field whose main aim is to explore computational and information-theoretic aspects of quantum mechanics. Key examples include quantum algorithms for classical problems, for instance to study large graphs, networks of quantum systems, where strange interactions connect nodes of separated quantum systems, communication networks featuring quantum-enhanced channels or channels for transmitting quantum information itself, and computational complexity theory under the presence of quantum devices and agents.
These topics enjoy lively interactions with a broad range of mathematical areas, including combinatorics, functional analysis, algebra and probability. Some of the state of the art on these themes will be presented by world experts.
