Experiment LHCb, one of the four main experiments at the LHC collider at CERN reports the observation of two new composite particles dubbed pentaquarks, with inner structure of four quarks and an antiquark. While other interpretations like a molecular-like bound …
New ambitious European project in astroparticle physics – CTA – will build a new international observatory focused on detection of high-energy photons (belongs to ESFRI roadmap). The project aims at discovery of a large number of yet unknown cosmisc sources …
Efficient construction of various quantum gates is a crucial prerequisite for practical quantum computing and communications. In our Letter (Phys. Rev. Lett. 114, 153602), we experimentally demonstrate how to implement an optimal controlled-unitary gate on individual photons using linear optics. This gate is particularly …

About the group:
The group focuses for a long time on research into optical quantum and nonlinear phenomena, as well as quantum information processing with light, research of nonstandard detection systems based on optics with sensitivity to single photons, special micro/nano optical surfaces and corresponding optical technologies and measurement methods. Other directions include the development of methods for the deposition and characterization of thin films using plasma and vapour deposition. The group develops optical non-contact measurement methods based upon interferometry in coherent speckle fields and white-light interferometry. The group also participates in prestigious international projects such as CERN-ATLAS (research on the nature of matter at the LHC accelerator at CERN in Geneva) and the Pierre Auger Observatory (research of ultra-high energy cosmic radiation).
RCPTM members (Chytka, L.; Hamal, P.; Hrabovsky, M.; Kvita, J.; Nozka, L.) have contributed to a number of ATLAS Collaboration articles. During 2016 (as of September), 3 Phys. Rev. Lett. (IF=7.728) papers, 21 J. High Energy Phys. (IF=6.220) have been published and a number of other papers in Phys. Rev. D, Phys. Lett. B, J. Instrum., and Eur. Phys. J. C.
Pierre Auger Collaboration (Horváth P.; Hrabovský M.; Nožka L.) has published 6 papers in 2016, e.g.: Measurement of the Radiation Energy in the Radio Signal of Extensive Air Showers as a Universal Estimator of Cosmic-Ray Energy, Phys.
