PRESS RELEASE –The Jülich Research Center has entered into a significant development partnership with ARQUE Systems. As part of this collaboration, a patented quantum computer with a 5-qubit quantum processor will be integrated into the JUNIQ (Jülich Unified Infrastructure for Quantum Computing) research platform of the Jülich Supercomputing Centre (JSC) next year. The semiconductor-based quantum computer is already designed to scale up to hundreds of qubits in the future.
Current quantum chips are extremely sensitive to environmental influences, making it difficult to construct stable and error-free quantum computers. Error correction requires millions of qubits, as thousands of physical qubits are needed to create a few logical, error-free units. However, scaling from the current 1,000 qubits to one million is an extremely challenging task.
ARQUE Systems’ Solution
ARQUE Systems uses semiconductor qubits based on transistor-like structures. Instead of traditional switches, they capture single electrons, utilizing their spin as quantum computing units. This technology is closely related to existing semiconductor manufacturing methods. To develop scalable structures and qubits, ARQUE Systems collaborates with the Helmholtz Nano Facility at FZJ and Infineon Dresden.
A key advantage of semiconductor qubits lies in their small size and the ability to integrate classical control electronics with qubit units on a semiconductor chip within a tile of about 100 µm². The chip can then be constructed with millions of such tiles, though this requires connectivity between the tiles. ARQUE Systems addresses this challenge by enabling the movement of qubits on the chip. Electrons are transported along so-called shuttle paths, like a conveyor belt, over several micrometers without losing the information encoded in their spin. Based on this principle, ARQUE employs a unique and patented processor architecture published in the renowned journal Nature Communications. This technology allows for the potential integration of millions of qubits on a single square-centimeter chip, including the necessary infrastructure such as connections and control electronics.
