Quantum information and physics with defect spins
We are a research group at QuTech, an institute for quantum science and technology at Delft University. Our team investigates solid-state spins and their applications for quantum information and physics. We use a combination of quantum optics, magnetic resonance and nanoscale fabrication to detect and control individual spins associated to defect centers. With these controlled systems of coupled spins, we aim to answer questions such as: How does decoherence emerge in complex quantum systems? Can we use quantum coherence to realize novel improved sensors? Can we protect quantum states and computations indefinitely so that large-scale quantum computations become possible? And does quantum mechanics continue to accurately describe such extended large-scale quantum systems?
We are currently looking for enthusiastic students and postdocs to join our team. Please contact Tim Taminiau if you are interested.
