Ambitious goal: Within the next three years, the world's most powerful quantum computer is to be created in Europe - a computer with 100 qubits and superconducting circuits. The quantum computer developed by ten European partners will be at the Research Center
Among other things, Jülich should and should simulate processes in chemistry and materials science and accelerate machine learning. The project "OpenSuperQ" gets ten million euros from the EU.

Quantum computers are considered computers of the future. Thanks to quantum physical phenomena such as superimposition and entanglement, the quantum bits consisting of atoms, ions or other smallest particles can process even complex tasks in parallel. They can therefore achieve much higher performance than conventional computers and can handle tasks that are too complex for conventional computers.

Accordingly, scientists all over the world are working feverishly to make quantum technology practically usable. Meanwhile, there are already the first commercial quantum computers, two different versions of such computers have been measured in a duel and the amount of qubits in quantum computers and simulators is increasing - up to 50 quantum bits have already been achieved.

Computing power of 100 quantum bits

But European researchers now want to go even higher: The goal of the project "OpenSuperQ" is to construct a functional quantum computer with 100 quantum bits by 2021. With this size, it would be the first quantum computer of this scale in Europe and also the world leader in comparable systems. "This is a size with which this quantum computer will leave today's classic-type supercomputers far behind for certain tasks, " the project says.

The quantum computer should be based on superconducting circuits and operated with open source software. The operating system can thereby be updated and improved by the users. "This open and inclusive approach is one of the most prominent features of 'OpenSuperQ', " says Project Coordinator Frank Wilhelm-Mauch of the University of Saarland. Ten partners from science and industry are involved in the project. display

All-purpose computer based on quantum

While quantum simulators can only solve certain tasks, the new "SuperQ" should be a true quantum computer - and thus, so to speak, an all-rounder. Nonetheless, he will focus on certain tasks: "Although he is designed as a general-purpose quantum computer, his main applications lie in the simulation of chemistry and material science as well as machine learning, " the researchers explain.

The location of the new European "quantum vehicle" will be Forschungszentrum J lich, and the cloud will then give users from all over Europe and the world access to the system. "This location will certainly fuel ideas from science that are rapidly being translated into applications, " says Wilhelm-Mauch. The project "OpenSuperQ" is part of the one billion Euro flagship program of the European Commission for the research of quantum technologies. It is funded with around ten million euros.
