New methods to implement quantum gates between trapped ions. We developed the theory for a new method to implement quantum gates between different trapped ions in an ion trap. The gates we developed have been very successfully implemented in a number of ion trap laboratories around the world, and is currently the preferred method in most experimental groups. Our theory thus form the foundation of the most advanced experimental system for quantum computation.
Quantum optics with surface plasmons. We showed theoretically that a single emitter placed near a metallic nanowire form an ideal system for controlling single photons. The coupling thus obtained enables an efficient coupling of single emitters and single photons. Furthermore it can be used to obtain strong optical nonlinearities at the single photon level, paving the way for applications such as single photon
transistors. The ¿rst experiments have con¿rmed these theories and further experiments are underway in a number of places.
Entanglement with Bose-Einstein condensates. We showed theoretically that Bose-Einstein condensates could be used to generate quantum entanglement of atoms. These theories form the basis of recent experiments achieving such entanglement of atoms in Bose-Einstein condensates.
Optimizing quantum memories. Quantum memory for atomic ensembles is pursued in a number of laboratories around the world, but only a limited efficiency is achieved. We developed the theory for how to achieve the optimal efficiency given the available experimental resources, and this has subsequently been used to increase the efficiency achieved in experiments. In addition our theory provided a simpli¿ed and unifying picture of the underlying physics in these experiments.
