Quantum engineering of light


Quantum dots as sources of photon pairs

Quantum dots can produce correlated and entangled photon pairs. In this project we investigate the means to maximize the coherence of excitation and the degree of time-bin entanglement.


Quantum state propagation in real-life networks

We aim at quantum light that can withstand the challenges of the real-life quantum network. Here, the performance of the entangled pair sources in quantum applications crucially depends on their quality but also the noise introduced by the communication channel. In this project we use experimental tests and theoretical simulations to address this issue.



This project focuses on fabrication of novel photonic devices for generation of entangled/hyper-entangled photon pairs. These are to be used in various quantum communication protocols. This project is receiving funding from the QuantERA ERA-NET Cofund in Quantum Technologies implemented within the European Union's Horizon 2020 Programme.
