The Institute for Quantum Optics and Quantum Information (IQOQI) of the Austrian Academy of Sciences dedicates its work to theoretical and experimental basic research in the areas of quantum optics and quantum information science. Research topics range from the foundations of quantum physics to their applications, for example for metrology, sensor technology and quantum information processing. Internationality, worldwide networking and highly actual research topics characterize the institute’s work which aims at conducting independent top-notch research.

We are investigating a novel way to interface light with the quantum states of trapped atomic ions. Our approach is to exploit a nonlinear optical process to change the frequency of single photons emitted and absorbed by trapped ions, from their natural values to those that are optimal for quantum networking. This frequency-shifter could act as a universal adapter for accessing and distributing the quantum states of trapped ions: between different traps and other quantum systems.
