Centrum Wiskunde & Informatica (CWI), Amsterdam, The Netherlands; has vacancies in the Network & Optimization research group for one PhD student and one postdoc in the research project:

"Approximation Algorithms, Quantum Information and Semidefinite Optimization".

This research project aims to explore the limits of efficient computation within classical and quantum computing, using semidefinite optimization as a main unifying tool. The positions involve research into the mathematical and computer science aspects of approximation algorithms for discrete optimization, quantum entanglement in communication, and complexity of fundamental problems in classical and quantum computing.
The project will be carried out in collaboration between Monique Laurent from the CWI Networks & Optimization research group, Ronald de Wolf from the CWI Algorithms & Complexity research group, and Nikhil Bansal from the department of mathematics and computer science of the Technical University Eindhoven. The positions are funded through an NWO-TOP grant.
