[ 2005-11-30 ] In Innsbruck succeeded for the first time as can be prove a larger number of atoms with one another. The researchers around Univ. Prof. Dr. Rainer sheet and Dr. Hartmut Haeffner report on it in the current expenditure for well doing RH. World-wide for the first time a "quantum byte in such a way specified (Qubyte) was realized", as eight ions controlled.
The production of a "quantum byte" is considered as important step on the way to the quantum computer. "that we achieved this goal as first, are a confirmation for the successful work of the Innsbrucker quantum physics", are pleased Professor Rainer sheet. "for our research is however crucially that we have a tool handy with this experiment now, with which we the processes of the quantum data processing very exactly study can", so sheet further. In close co-operation with the theoreticians Dr. Otfried Guehne and Dr. Wolfgang Duer from the Innsbrucker working group of Univ. Prof. Dr. Hans J. Briegel showed the scientists around Rainer sheet and Hartmut Haeffner that them four, five, six, to sieve or eight ions on controlled way to be able. The calcium ions are caught in addition with electromagnetic fields in an ion trap, arranged next to each other in a row and with thought out laser technology in w-conditions so mentioned.
Aufwaendige measurement
The actual difficulty in the experiment was the proof that the particles are actually with one another. Approximately 650,000 measurements had to be accomplished, in order to be able to describe the eight "quantum bits (Qubits)" by numbers. However this measuring process took up over ten hours. The computation of the numbers and their conversion to a diagram on a high speed computer of the university took directly several days. This already suggests the high superiority of the quantum data processing opposite conventional computers. "which can with the eight Qubits in approximately one millisecond happened, with a normal computer only in many hours computed and", explain Professor Blatt are characterized. The successful experiment proves also: Ion traps, how they are used in Innsbruck, represent the at present most promising technology for the conversion of larger computing areas. In the case of the eight ions this computing area consists of 65.536 elements independent to the majority.
Quantum center Innsbruck
Already in the last year the first Teleportation with atoms succeeded to the group around Professor Rainer sheet. The current experiment underlines once more the prominent position of the Innsbrucker quantum physics, which enjoys both national and internationally high reputation. With the close co-operation of theoreticians and experimental physicists and the rossen density at highly-qualified researchers around professors Rainer sheet, Hans's J. Briegel, Rudolf Grimm and Peter Zoller developed in Innsbruck in the last years a center of quantum physics. The Austrian Academy of Sciences with Institut for quantum optics and quantum information (IQOQI), the Austrian science fund with a Austria-far special research range and the European union make crucial contribution in addition as well as country Tirol, city Innsbruck and the Tiroler industry. The recent success of the Innsbrucker quantum physicists clears the way for a still better understanding of future quantum computers and offers to the physicists for the first time the possibility for detailed analyses of the cross-setting of several particles.
