Interview to Prof. Rainer Blatt Research Director of the Institute for Quantum Optics and Quantum Information (IQOQI), Innsbruck, Austria

Experimental physicist Rainer Blatt, Research Director of IQOQI has carried out trail-blazing experiments in the fields of precision spectroscopy, quantum metrology and quantum information processing. He works with atoms caught in ion traps which he manipulates using laser beams. This work is based on suggestions made in the mid 1990s by theorists Ignacio Cirac and Peter Zoller. In 2004, using their suggested set-up, Blatt’s working group succeeded for the first time in transferring the quantum information of one atom in a totally controlled manner onto another atom (teleportation). The science journal Nature reported the experiment and gave it pride of place on the cover. Two years later, Rainer Blatt’s working group already managed to entangle up to eight atoms in a controlled manner. Creating such a first “quantum byte” (qubyte) was a further step on the way towards a quantum computer. In 2011 the team managed to push this record to 14 entangled atoms. Furthermore Rainer Blatt took important steps towards successful quantum error correction and the building of quantum simulators.
