Matter and light for quantum computing (ML4Q)

Logo of the Cluster of Excellence Matter and light for quantum computing (ML4Q)

Matter and Light for Quantum Computing (ML4Q) is a Cluster of Excellence funded in 2018 within the Excellence Strategy by the German Research Foundation (DFG).
It is a cooperation by the universities of Cologne, Aachen, and Bonn, as well as the Research Center Jülich. The aim is to develop the best hardware platform for quantum information technology, and to provide comprehensive blueprints for a functional quantum information network.

ML4Q builds on the complementary expertise at the partner institutions in the key research fields: solid-state physics, quantum optics, and quantum information science. PIs of the JARA Institute for Quantum Information are major contributors in the three focus areas “Majorana qubits” (Hassler), “Decoherence, measurements, and error correction” (DiVincenzo, Bluhm and Schreiber) and Quantum connectivity” (Bluhm, Kardynal).

Prof. DiVincenzo is member of the European FET Flagship project OpenSuperQ, which aims at designing, building and operating a quantum information processing system of up to 100 qubits and at sustainably making it available at a central site for external users.

Long-range quantum bus for electron spin qubits in silicon (Si QuBus)

JARA IQI participates to the QuantERA network with the project "Long-range quantum bus for electron spin qubits in silicon" (Si QuBus). QuantERA is a network of 31 organisations from 26 countries that supports international research projects in the field of Quantum Technologies (QT). QuantERA answers the growing need for collaborative endeavours and common funding schemes within QT research, which due to its highly interdisciplinary nature cannot be confined to an individual institution or state.

The goal of the Si QuBus project is to demonstrate a fault-tolerant quantum bus (QuBus) that coherently transfers a single electron with an arbitrary spin qubit state between quantum dots separated by 1 to 10 microns. More information can be found here.
