V računalniku je z uporabo nizov ujetih ionov implementiran kvantni informacijski procesor za izvajanje kvantnih operacij. Predstavljena bo razpoložljiva kvantna orodjarna in možnost razširljivosti tega pristopa. Metodologija kvantnega računalništva bo ponazorjena z analognimi in digitalnimi kvantnimi simulacijami. Z uporabo kvantnega orodja za Ramseyevo interferometrijo, izboljšano s pomočjo kvantne prepletenosti, so določeni optimalni parametri za kvantno meroslovje. Izvedba univerzalnega nabora vrat, odpornega na napake, bo osvetljena na primeru dveh logičnih kubitov znotraj kvantnega računalnika z ujetimi ioni.

Using strings of trapped ions, a quantum information processor is implemented to carry out quantum operations. An overview of the available quantum toolbox will be presented and the scalability of this approach will be discussed. The quantum computing methodology will be exemplified through analog and digital quantum simulations. By utilizing the quantum toolbox for entanglement-enhanced Ramsey interferometry, optimal parameters are determined for quantum metrology. The implementation of a fault-tolerant universal set of gates will be highlighted on two logical qubits within the trapped-ion quantum computer. With Alpine Quantum Technologies, a commercially available NISQ-type quantum processor has been developed and is already accessible for industrial applications.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><b>About the lecturer</b>: Rainer Blatt is a full member of the Austrian Academy of Sciences, a professor of physics at the University of Innsbruck, and a senior scientist at the Institute for Quantum Optics and Quantum Information.
