The Centre for Quantum Optical Technologies

The Centre for Quantum Optical Technologies (QOT) explores quantum phenomena, such as superpositions and entanglement, in optical and optically controlled system, with the long-term prospects of their practical utilisation. In the long-term, the outcomes of this research are expected to be used in practice and translated, for example, into more sensitive sensors or safer communication methods.

The Centre has been established by the University of Warsaw in partnership with the University of Oxford under the International Research Agenda Programme operated by the Foundation for Polish Science – project number MAB/2018/4. The Centre was established with the funding amount of 34 999 430,00 PLN in 2018. It is hosted by the Centre of New Technologies, an interdisciplinary scientific unit of the University of Warsaw focused on research and technology development. QOT maintains strong ties with the Faculty of Physics at UW. The Director of QOT is Prof Konrad Banaszek.

In 2024 QOT received grant funding of 30 000 000,00 PLN within the MAB FENG programme from the Foundation for Polish Science to continue operation and bring quantum optical technologies into practical applications.

 
The QOT project is supported by the European Union. See more.

QOT currently consists of five laboratories focusing on:

  • Quantum Technologies, QT Lab,
  • Quantum Memories, QM Lab,
  • Quantum Information and Inference, QI2 Lab,
  • Quantum Resources and Information, QR+I Lab,
  • Quantum Optical Devices, QOD Lab.
