Our research

Spectral-temporal engineering of quantum light

We research the potential of spectral-temporal encoding for processing of quantum information. Our interests include experimental implementations of multidimensional quantum-enhanced metrology. We explore highly efficient, fibre-compatible quantum cryptography protocols. We look for applications of time-energy entanglement.

Photonic interfaces for quantum networks

We experimentally investigate methods for coherent modification of spectro-temporal mode structure of optical pulses at the single photon level. We are building highly efficient electro-optic mode converters for single-photon pulses. We explore properties of highly dispersive optical media.

Quantum temporal Fourier optics

We explore applications of the concept of time lens and ultrafast all-optical information processing in the field of quantum optics. We explore new opportunities offered by these techniques for quantum information processing. We address technical challenges associated with applying these concepts to non-classical light.

The Group

Who we are

We are a young dynamic group within the Optics Division of the Faculty of Physics (FUW) at the University of Warsaw (UW). FUW is a world-class research centre covering a broad area of physics and is the leading physics research institution in Poland. It hosts numerous groups both in optics (Ultrafast Phenomena Lab, Quantum Memories Lab, Photonic Nanostructures Facility, Information Optics Lab, Cold Atoms, Femtosecond Spectroscopy) as well as quantum information, quantum metrology and communications theory. This gives us an ideal setting for our research.

Our Lab

We work in a state-of the art optical lab with a lot of cutting-edge equipment, including low timing jitter supercoducting single-photon-counting detectors. We appreciate the support of Konrad Banaszek, Czesław Radzewicz and numerous funding programmmes (EU Structural Funds, National Science Centre of Poland).

Find Us

We are located at the Ochota Campus of the University of Warsaw, in the interferometrically stable basement of the Geophysics Building.

We are a short tram ride from the centre of Warsaw. The Warsaw Fryderyk Chopin Airport is just a 20-minute bus ride away. On sunny days we escape the darkness of the lab to enjoy the adjacent Pole Mokotowskie Park.
