Quantum computers to become portable


Together with the University of Innsbruck, the ETH Zurich and Interactive Fully Electrical Vehicles SRL, Infineon Austria is researching specific questions on the commercial use of quantum computers. With new innovations in design and manufacturing, the partners from universities and industry want to develop affordable components for quantum computers.

Ion traps have proven to be a very successful technology for the control and manipulation of quantum particles. Today, they form the heart of the first operational quantum computers and, along with superconducting quantum bits, are considered the most promising technology for the construction of commercial quantum computers.

Infineon Austria

Since last year, engineers and researchers have been jointly exploring how ion traps can be built using semiconductor manufacturing technologies and which quantum chip architectures benefit in particular from the increased precision and scalability of modern semiconductor manufacturing in the cooperation between Infineon Technologies Austria and the research partners University of Innsbruck, ETH Zurich and Interactive Fully Electrical Vehicles SRL from Italy, funded by the EU as part of the Horizon 2020 project PIEDMONS.

In addition, the research partners want to find out whether ion traps can also be operated at room temperature thanks to innovative trap geometry. The researchers aim to produce more robust quantum systems and miniaturize the entire system by integrating the necessary electronics on-chip. On-chip means that the newly developed electronics are integrated directly next to the quantum system - in the laboratory they currently take up a lot of space next to the experimental setup. The vision is to make quantum computers portable for the first time.

Young researcher with a visionary doctoral thesis

In her doctoral thesis, Silke Auchter (26) researches ion traps. These ion traps are to be further developed using semiconductor manufacturing technologies. In this way, the traps can be produced very uniformly and precisely and more easily combined with miniaturized electronics and optics.

In addition, more complex and comprehensive trap concepts that are robust against external interference can be implemented. The ions are used as quantum bits, the quantum mechanical counterparts to the bits in conventional computers. Researchers trap ions in the laboratory in an electromagnetic field whose exact shape is determined by the structure of the ion trap.

Microfabricated traps have not yet had an optimal grip on the ions. If it is possible to construct these quantum chips in such a way that the ions remain more stable, this will help the quantum researchers in Innsbruck and Zurich in their quest for larger quantum registers and more complex quantum algorithms.

In addition, robust quantum states are required for use outside laboratory conditions, i.e. at room temperature and ultimately even mobile. With the first quantum chip prototypes, developed in the MEMS department in Villach, experiments by Silke Auchter are already being carried out.

Auchter is a PhD student at Infineon and is supervised by Rainer Blatt, an internationally renowned quantum physicist, at the Department of Experimental Physics of the University of Innsbruck, Austria. The aim of her research is to produce a microfabricated ion trap in which the ions are trapped stably at room temperature.

At present, the prototypes of quantum computers still have to be cooled extensively, which is a major obstacle to the industrial production of quantum computers. In her experiments, Silke Auchter therefore tries to capture ions so efficiently that quantum chips also function at room temperature and even more complex chip architectures can be built.

Im Focus: The working of a molecular string phone

Researchers from the Department of Atomically Resolved Dynamics of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg, the University of Potsdam (both in Germany) and the University of Toronto (Canada) have pieced together a detailed time-lapse movie revealing all the major steps during the catalytic cycle of an enzyme. Surprisingly, the communication between the protein units is accomplished via a water-network akin to a string telephone. This communication is aligned with a ‘breathing’ motion, that is the expansion and contraction of the protein.

This time-lapse sequence of structures reveals dynamic motions as a fundamental element in the molecular foundations of biology.

Im Focus: Milestones on the Way to the Nuclear Clock

Two research teams have succeeded simultaneously in measuring the long-sought Thorium nuclear transition, which enables extremely precise nuclear clocks. TU Wien (Vienna) is part of both teams.

If you want to build the most accurate clock in the world, you need something that "ticks" very fast and extremely precise. In an atomic clock, electrons are...

Im Focus: Graphene sets the stage for the next generation of THz astronomy detectors

Researchers from Chalmers University of Technology have demonstrated a detector made from graphene that could revolutionize the sensors used in next-generation space telescopes. The findings were recently published in the scientific journal Nature Astronomy.

Beyond superconductors, there are few materials that can fulfill the requirements needed for making ultra-sensitive and fast terahertz (THz) detectors for...

Im Focus: Physicists from Stuttgart prove the existence of a supersolid state of matte

A supersolid is a state of matter that can be described in simplified terms as being solid and liquid at the same time. In recent years, extensive efforts have been devoted to the detection of this exotic quantum matter. A research team led by Tilman Pfau and Tim Langen at the 5th Institute of Physics of the University of Stuttgart has succeeded in proving experimentally that the long-sought supersolid state of matter exists. The researchers report their results in Nature magazine.

In our everyday lives, we are familiar with matter existing in three different states: solid, liquid, or gas. However, if matter is cooled down to extremely...

Im Focus: World record for tandem perovskite-CIGS solar cell

A team headed by Prof. Steve Albrecht from the HZB will present a new world-record tandem solar cell at EU PVSEC, the world's largest international photovoltaic and solar energy conference and exhibition, in Marseille, France on September 11, 2019. This tandem solar cell combines the semiconducting materials perovskite and CIGS and achieves a certified efficiency of 23.26 per cent. One reason for this success lies in the cell’s intermediate layer of organic molecules: they self-organise to cover even rough semiconductor surfaces. Two patents have been filed for these layers.

Perovskite-based solar cells have experienced an incredibly rapid increase in efficiency over the last ten years. The combination of perovskites with classical...
