Andrzej Opala received the prize for the best poster presented at the Wilhelm und Elise Heraeus Seminar “Lattice-based Quantum Simulation”. Congratulations!
Exceptional efficiency of polariton neural networks
Machine learning and artificial intelligence are an important part of the economy. However, the data- and power-hungry algorithms put a strain on computing systems, which have to fulfill the requirements of fast and efficient data processing. In our work published…
Polariton neural networks
In collaboration with experimental groups from Italy and Poland, we demonstrated the first functional neuromorphic polariton networks performing machine learning tasks. In the two papers published in Nano Letters, we have shown that polariton neural networks are able to perform handwritten digit recognition and…
Massive photons in an artificial magnetic field
An international research collaboration that combined academics from Poland, the UK and Russia has created a two-dimensional system – a thin optical cavity filled with liquid crystal – in which they trapped photons with unique properties. The localized photons behaved like…
Ultrafast neural networks with exciton-polaritons
We propose that exciton-polariton lattices can be used as a central component of neural networks in the so-called reservoir computing architecture. Theoretical estimates demonstrate orders of magnitude improvement of processing speed with respect to state-of-the-art realizations thanks to the ultrafast excitonic nonlinearity. This research…
Josephson vortices in polariton fluids of light
A twist of quantum phase of a polariton condensate imposed by two external lasers leads to creation of a long Josephson juncion. By increasing the particle density, we drive the system to an instability that results in the creation of…
New members
We welcome dr Vanik Shahnazaryan and dr Paolo Comaron, who started working in our group as postdoctoral fellows.
Single shot condensation and the hole burning effect
Single shot measurements of exciton-polariton condensation in a high quality sample revealed instability and hole burning effects leading to intricate star-like patterns. The research has been published in Nature Communications. The experiment was realized in the group of Elena Ostrovskaya from…
Quant-ERA project
Our group has commenced the realization of the InterPol project of the Quant-ERA programme, a EU cofund Initiative in Quantum Technologies, see the Interpol project website. The project, carried out in collaboration with world-leading groups from UK, France, Germany and Israel, aims to…
New member
Mr Andrzej Opala will join our group as a PhD student starting from 1 October.
