2024 Materials Science Lecture series - Super-Resolution Quantum Fluorescence Microscopy
We are excited to invite you to the upcoming lecture "Super-Resolution Quantum Fluorescence Microscopy", presented by Dr. Konstantin Katamadze. His research focuses on experimental quantum optics, quantum state engineering, and quantum measurements of various quantum states of light, including single-photon fields produced by single-photon emitters, two-photon fields generated by spontaneous parametric down-conversion, and thermal radiation. In his talk, he will introduce a novel technique that enables sub-diffraction localization of dye molecules and quantum dots through point spread function shaping and photon statistics measurements.

Super-Resolution Quantum Fluorescence Microscopy
Fluorescence microscopy is a cornerstone of many biological applications, utilizing dye molecules or quantum dots to generate images. According to the Rayleigh limit, two emitters cannot be resolved if their separation is smaller than the width of the point spread function (PSF), which is proportional to the wavelength. While various methods have been developed to surpass this limit, they often come with significant technical challenges and restricted applicability. In this talk, we introduce a novel technique that enables sub-diffraction localization of dye molecules and quantum dots through PSF shaping and photon statistics measurements. Our theoretical analysis demonstrates that this approach can achieve up to a tenfold resolution enhancement in realistic imaging scenarios, offering a practical and versatile solution to overcome traditional resolution limits.
About our guest
Konstantin Katamadze studied at Lomonosov Moscow State University (MSU), where he earned his Specialist degree in 2010 and his PhD in 2013. Following his studies, he continued his work at MSU and concurrently at the Valiev Institute of Physics and Technology in Moscow, serving as a Junior Researcher and later as a Senior Researcher until 2022. He then joined the Technology Innovation Institute in Abu Dhabi as a Lead Researcher. His scientific interests focus on experimental quantum optics, quantum state engineering, and quantum measurements of various quantum states of light, including single-photon fields produced by single- photon emitters, two-photon fields generated by spontaneous parametric down-conversion, and thermal radiation. He has also explored applications of these studies in quantum sensing, quantum computation, and quantum cryptography, advancing the practical implementation of quantum technologies.
