Quantum Computing and Metrology
Trapped-ions are a leading technology in quantum information studies. We have implemented in our lab a small scale quantum computer on an array of trapped ions. In our research we focus on active ways to prevserve coherence of quantum superpositions under noise, such as dynamic decupling, the use of decoherence free subspaces or quantum error-correction codes. We further investigate how the long coherence times obtained can be used to advance precision metrology.
