There are many ways to realise qubits and thus quantum computers in hardware. It is not yet clear which approach is the best way to realise a universal, error-corrected quantum computer. That is why we are commissioning the development of different hardware platforms and strengthening the quantum computing ecosystem by commissioning the necessary basic technologies and applications. This technological diversity and depth are one of our core principles.

Ion traps

Qubits from ion traps are characterised by particularly long coherence times, high gate quality and high entanglement capability.

Neutral atoms

Quantum computers with qubits made of neutral atoms are particularly easy to scale.

NV centers

Thanks to their high reliability and – relatively – simple handling, qubits from NV centres are a promising technology approach for quantum computing.

Photons

Working with light is routine: photonic quantum computers fit on a chip and therefore promise high scalability.

Spin-enabling technologies

We develop technologies for the targeted and reproducible production of spin qubits with known characteristics.

Analogue computing

Analogue computers can be an energy-saving alternative for machine learning and large simulations and a complementary element for hybrid computing.
