Beschreibung:
<jats:p>The approximation of quantum states with artificial neural networks has gained a lot of attention during the last years.
Meanwhile, analog neuromorphic chips, inspired by structural and dynamical properties of the biological brain, show a high energy efficiency in running artificial neural-network architectures for the profit of generative applications.
This encourages employing such hardware systems as platforms for simulations of quantum systems.
Here we report on the realization of a prototype using the latest spike-based BrainScaleS hardware allowing us to represent few-qubit maximally entangled quantum states with high fidelities.
Bell correlations of pure and mixed two-qubit states are well captured by the analog hardware, demonstrating an important building block for simulating quantum systems with spiking neuromorphic chips.</jats:p>
