Today, quantum computers are considered to be the computing machines of the future. They use so-called qubits instead of the conventional bits of classical computer technology. The special properties of these qubits allow the quantum computer to assume all states that can be represented with the qubits simultaneously, while conventional computers can only work with one of the combinations that can be represented by the available bits per computing step. Quantum computers can thus be used to solve tasks that conventional computers fail at. Processes at the molecular level can be simulated so that, for example, the mode of action of new active ingredients can be predicted for the pharmaceutical industry. Likewise, quantum computers can find ways to develop highly efficient battery storage or solve complex problems in traffic management.
Objectives and approach
The present collaborative project aims to build the demonstrator of a quantum computer based on superconducting circuits, as well as the peripherals necessary to interface the quantum computer to conventional computer systems. The work includes research into microwave circuits to control the qubits, research into integration methods for superconducting circuits, and extends to the development of customized compilers and runtime environments for the quantum computer. The associated quantum processor is expected to be able to compute with up to 100 qubits, and would thus be capable of representing ten to the power of thirty states simultaneously (which is about ten billion times the estimated number of stars in the universe).
Innovation and perspectives
The goal of the work is, among other things, to ensure reliable operation of such a quantum computer and, on the other hand, to create the periphery to make the computing power of this computer available to a broad group of users via cloud computing.
