Dissipation induces decoherence in a quantum system which is usually detrimental for quantum state engineering and quantum information processing. However, by engineering dissipation properly, it can actually be a useful resource for preparing exotic quantum strongly-correlated states.

Topological protection allows realization of integrated photonic devices that are robust against certain fabrication-induced disorder. However, it is usually challenging to achieve device reconfigurability along with topological robustness.

A quantum light source has many potential applications in quantum information sciences. However, any on-chip realization is marred by the nanofabrication-induced disorder.

We reduce measurement errors in a quantum computer using machine learning techniques. We exploit a simple yet versatile neural network to classify multi-qubit quantum states, which is trained using experimental data.
