In the new lab course Experimental Quantum Technologies students have created highly entangled GHZ-states. They could show experimentally that GHZ-states have better interferometric properties than QuBits.

This marks a new phase in teaching Quantum Technologies, as highly advanced quantum resources become accessible to researchers and students alike.

The experiments were carried out on the Fraunhofer-IBM QSystem One networkExternal link, with kind support by the QuantumNow initiative of the Fraunhofer-Gesellschaft.
