Institute of Quantum Computing

The IKON Institute of Quantum Computing aims to develop quantum technologies for precision instruments in aerospace and to develop prototypes in close cooperation with the industry. It is therefore interdisciplinary: Theoretical basic research and experimental test results lead to engineering implementation.

New developments based on innovative quantum technological processes will make a significant contribution to solving social and technological challenges. For example, novel systems of quantum sensors – for example high-precision inertial sensors – could be used for space and terrestrial applications that use the entire spectrum of new developments in quantum physics and quantum optics. On this basis, groundbreaking geodetic applications and advanced reference systems in space and time could emerge.

Quantum computing makes use of the effect of superposition or the interference of matter waves. Under certain conditions, particles – electrons, atoms or nanoparticles – spread out as waves. These waves can be superimposed in a similar way to light or water waves. Even the slightest influences can lead to noticeable changes in the interference with patterns of the superimposed matter waves. This can be recorded with highly sensitive measurements. In contrast to the massless light particles, photons and matter fall in the earth’s gravitational field, which is used, for example, for tests of Einstein’s general theory of relativity.

Another effect that is based on quantum technologies is the entanglement between two particles. If one of the two particles is manipulated, the state of the partner particle changes even at the greatest spatial distances. This allows extremely secure information transfer when used in conventional forms of communication since each eavesdropping attack changes the result of the measurement and is thereby uncovered. The application of this quantum technology to satellites will significantly increase the security of the global transmission of information.

The research work of the four main departments Quantum Metrology, Quantum Information and Communication, Quantum Nanophysics and Quantum Control of Loaded Matter Waves is complemented by the three cross-sectional departments: Quantum Engineering, Integration of Micro- and Nanosystems and Theoretical Quantum Physics.

Within the framework of the “Optical Frequency Measurement” department, a strong cooperation with NIST in the USA (National Institute of Standards) is planned. One of the departments (relativistic modeling) will be located in Zurich.
