A new signal processing method developed by UW students

Students at the Faculty of Physics of the University of Warsaw and researchers from the QOT Centre for Quantum Optical Technologies have developed an innovative method that allows the fractional Fourier Transform of optical pulses to be performed using quantum memory. This unique achievement is first to present an experimental implementation of transformation in this type of a system.

Defying gravity

Physicists from the Utrecht University and the UW Faculty of Physics have observed - for the first time experimentally - the Brazil nut effect in a mixture of charged colloidal particles. The findings were published in “The Proceedings of the National Academy of Sciences” (PNAS).

An isolated black hole roaming our Milky Way galaxy

The Milky Way galaxy is expected to host over 100 million isolated black holes. Two independent teams of scientists, including astronomers from the Astronomical Observatory of the University of Warsaw, have for the first time discovered what may be a free-floating black hole.

Quantum Technologies Cluster kicks off at CeNT UW

Optical communications, quantum cryptography, sensors in medical diagnostics – the development of these technologies can revolutionise the economy of those countries that are able to exploit the potential of Quantum Physics. Forthcoming transformation will involve academic institutions, research centres and entrepreneurs which, on 23rd May, set up the Cluster Q – Quantum Technologies Cluster.

Eyeglasses for the Ukrainians

Eyesight examinations by students of optometrics, the UW Faculty of Physics, are available free of charge for the citizens of Ukraine who had to flee the war zone in their country. During the fortnight, over thirty patients received free consultation.

New article in “Nature Physics”

Researchers from the UW Faculty of Physics, University of Cambridge, Queen Mary University of London and University of Sofia have shown that slow cooling of a suspension of oil droplets with surfactant in water may lead to non-spherical shapes of the droplets, which can produce filamentous structures resembling bacterial flagella. The filaments induce motion of the droplets, and the process is ful

UW researchers proved the existence of the imaginary part of quantum mechanics

An international research team, to which scientists from the UW Centre for Quantum Optical Technologies (QOT) belong, has proved that the imaginary part of quantum mechanics can be observed in action in the real world. The research results have been published in the journals “Physical Review Letters” and “Physical Review A”.

“Return from the Stars”: Read with UW

Some say that Stanisław Lem is one of the most popular among physicists. Prof. Krzysztof Turzyński from the UW Faculty of Physics is his faithful reader. Do we need knowledge in physics to understand Lem's works? Can women be astronauts, according to Lem? To find out, watch the second episode of #CzytajzUW (Read with UW) series.

UW physicist awarded with the ICO Prize

Prof. Wojciech Wasilewski from Centre of New Technologies and the UW Faculty of Physics has received a prestigious International Commission for Optics Prize (ICO). It is awarded to an individual who has made a noteworthy contribution to optics.

The UW scientists’ article in „Nature Physics”

Demonstration of fundamentally distinct type of lattice clock is one of the main topics of the research conducted by the international team of scientists. Two of them are the UW Faculty of Chemistry employees. The description of the scientists’ work is presented in the article entitled “Molecular lattice clock with vibrational coherence” that was published in “Nature Physics”.

The UW scientist as a co-author of the paper in “Nature Photonics”

The article entitled “Suppressed Auger scattering and tunable light emission of Landau-quantized massless Kane electrons” was published in “Nature Photonics” magazine. One of its co-authors is Prof. Marek Potemski, a Visiting Professor at the UW Faculty of Physics. The paper introduces new steps in the research connected with the future technology of Landau level lasers.

Quantum interference in service of information technology

Scientists from the Faculty of Physics, University of Warsaw, in collaboration with the University of Oxford and the NIST agency, have shown that quantum interference enables processing of large sets of data faster and more accurately than with standard methods. Their studies may boost applications of quantum technologies in e.g. artificial intelligence, robotics and medical diagnostics.

FNP Prize for the UW physicist

Prof. Krzysztof Pachucki from the Faculty of Physics of UW received the Foundation for Polish Science Prize “for precise quantum electrodynamic calculation of spectroscopic parameters of lightweight atoms and molecules.” These findings are the basis for precise determination of fundamental physical constants.

Sergei Kovalyov with an honorary degree of UW

Dr. Sergei Kovalyov, a Russian biophysicist, politician and human rights activist, received an honorary doctorate degree of the University of Warsaw. The ceremony was held on 14th March.

Centre of Quantum Optical Technologies

Prof. K. Banaszek from UW has received a grant awarded by the Foundation for Polish Science under the International Research Agendas Programme. His project is devoted to quantum optical technologies.
