Project Objective

MIQRO is developing a modular quantum computer consisting of “quantum cores” in which stored ytterbium ions serve as qubits. They are controlled not by laser light, but by microwaves. This is made possible by MAGIC (Magnetic Gradient Induced Coupling), a method developed at the University of Siegen: A magnetic field gradient allows individual ions to be addressed and coupled with one another. This approach promises reproducible qubits, very low crosstalk, reduced cooling requirements, and integrable control electronics. The developed quantum core is expected to be scalable to up to a thousand qubits without any technological barriers.

Our Task

The Chair of Experimental Quantum Optics (Prof. Dr. Christof Wunderlich) is contributing the MAGIC concept and conducting experiments on the trapping, spectroscopy, and coherent control of ions in microstructured traps. Partners include Leibniz University Hannover and the PTB (chip design and processor chip), the Technical University of Hamburg (characterization and benchmarking under Prof. Dr. Martin Kliesch, formerly at HHU Düsseldorf), QUARTIQ GmbH (control electronics), and the Siegen-based spin-off eleQtron GmbH as an associated partner.
