Some of her most recent research addresses the challenges inherent in using laser light and photon energy to study static and dynamic properties of atoms and molecules, on ultrafast timescales demonstrated a new measurement scheme, frequency-resolved optomolecular gating, which resolves the temporal amplitude and phase of the harmonic emission from excited molecules.
Attosecond interferometry reveals the internal coherence in ultrafast electronic phenomena. I will describe advanced interferometry schemes, resolving a range of processes – from tunneling and photoionization in atomic systems to ultrafast chiral phenomena and attosecond scale currents in solids.

Nanophotonics offers the platform for large-scale implementation of quantum processors. Multirail Architecture provides a novel class of small or intermediate-scale quantum processors, that, although far from fault tolerant, support the execution of heuristic quantum algorithms, which might enable a quantum advantage, for example, when applied to combinatorial optimization problems. This class of devices should allow for “quantum supremacy”, that is, solving a problem that is classicaly intractable in a reasonable time, with the advantage to be embedded as “quantum coprocessor” in the motherboard of a classical computer or a mobile device, opening the way to investigation on Quantum Based Artificial Intelligence, and production of new crypto-devices to implement quantum communication and cryptography protocols. The vision is to create “a reconfigurable light brain” able to learn and take autonomous decisions.

Martina Havenith holds the chair of Physical Chemistry II at Ruhr-University Bochum. She is the founder and speaker of the Excellence Cluster RESOLV (Ruhr Explores Solvation), granted within the German Excellence Initiative in 2012 and 2018, and the Director of the research building ZEMOS (Center for Molecular Spectroscopy and Simulation of Solvent Driv-en Processes). Her research pioneered terahertz (THz) spectroscopy as a sensitive method to study solvation of small solutes and biomolecules.
In recent years terahertz (THz) technology has been stablished as a novel tool to study the dynamics of the most important solvent: water. Water has to be attributed a much more ac-tive role in the function of hydrated molecules, which we begin to understand via THz studies accompanied with novel theoretical insights. We developed nonlinear THz spectroscopy to record precise absorption of solvated samples with a precision of 0.2 %. This allowed to de-tect subtle changes in the dynamical (sub-psec) orientation of water molecules. Our study unravelled unknown phases of water under nanoconfinement and provided a local, label free probe on protonation state of amino acids. Both parameters are of importance to understand the enormous reactivity in cleft of enzymes compared to chemically designed catalyst.

Matthias Kling graduated in physics from the University of Göttingen in Germany, where he also obtained in PhD in 2002. Between 2007 and 2012, after postdoctoral employments at UC Berkeley (USA) and AMOLF (The Netherlands), he led an Emmy Noether and Heisenberg research group at the Max Planck Institute of Quantum Optics in Garching, Germany. Following a brief period as assistant professor at Kansas State University (USA), he was appointed in 2013 to his present position as professor in Ultrafast Imaging and Nanophotonics at the Ludwig-Maximilians-Universität Munich in Germany. Since 2019 he holds a co-appointment as Max Planck Fellow at the Max Planck Institute of Quantum Optics.
Studies of the interaction of high, and ultrashort laser fields with nanostructures provide insight into local fields and charge dynamics under extreme conditions. The relevant strong-field dy-namics unfolds on sub-cycle time scales. For sufficiently high fields, nanoplasmas can be generated. In the presentation, I will introduce the physics from the weak to the strong-field regime. Examples of joint experimental and theoretical work will illustrate different interaction regimes. The extreme conditions reached in high-intensity near-fields can also aid in molecular processes of adsorbed species on the nanostructures. Recent studies on near-field induced molecular dynamics will illustrate the unique conditions provided by the intense light-nanostructure interaction.

Michael Kneissl is a professor of “Experimental Nanophysics and Photonics” at TU Berlin, Germany and holds a dual appointment at the Ferdinand-Braun-Institute (FBH) in Berlin. His research interests include wide bandgap semiconductors and novel optoelectronic devices in particular UV-LEDs and laser diodes. He has co-authored over 400 publications and holds more than 55 patents in the area of group IIInitride device technologies. He is co-founder of UVphotonics NT GmbH and was named Fellow of the Institute of Electrical and Electronics Engineers (IEEE) for his contributions to the development of wide bandgap semiconductor laser diodes and ultraviolet LEDs in 2016.
Driven by high volume applications like water purification, surface disinfection, and air treat-ment systems the development of AlGaN-based light emitting diodes in the deep ultraviolet spectral range (DUV-LEDs) has greatly accelerated. This presentation will provide an over-view of state-of-the art in DUV-LED device technologies and present recent advances in the development of high quality AlGaN materials by metalorganic vapour phase epitaxy. We will discuss different approaches to improve the quantum efficiency of UV light emitters, including the growth of low defect density AlN layers on sapphire substrates. High-power AlGaN quan-tum well LEDs near the germicidal effectiveness peak around 265 nm will be demonstrated and the wavelength limits of deep UV-LEDs with emission as short as 217 nm will be ex-plored. These far UV-LEDs are ideally suited for sensing applications like the monitoring of combustion engines or nitrates in water and may also be utilized for the inactivation of multi-drug-resistant bacteria without damaging the human skin. First applications of far UV-LEDs will be demonstrated including a spectrally pure 233 nm irradiation system for the in-vivo inac-tivation of hospital germs.

Bill is a Senior Distinguished Scientist with NTT Basic Research Laboratories and the director of it's Research Center for Theoretical Quantum Physics. His research interest range from foundational issues of quantum theory through to quantum information processing and its practical realization. In particular, he has focused on quantum networks and their design. Recently he has been exploring quantum multiplexing and aggregated quantum networks. His is also a fellow of the OSA and APS.
Quantum networking is known to enable the transmission of information in ways unavailable to us in the classical world and will be integrable part of many future non-local quantum technol-ogies ranging from distributed quantum computation to remote quantum sensing and various forms of quantum communication. They will rely on the creation entangled pairs between vari-ous parties on that lossy network (Alice, Bob, Charlie, ...) that can be either directly used or stored in quantum memories. The efficient creation of such entangled pairs will be a critical tasks going forward. Here we introduce the concept of quantum multiplexing which encodes more that a single qubit of information onto a photon. It allows one to create high fidelity en-tangled pairs in a shorter time with a significant reduction in both the number of photons and memories needed. We further show how the coherent aggregation of many quantum channels together opens new network possibilities unavailable with conventional telecommunication.

Carsten Rockstuhl received a Ph.D. degree from the University of Neuchâtel, Neuchâtel, Switzerland, in 2004. His work there focused on investigating light fields around micro- and nano-optical structures. After a PostDoc period at AIST in Tsukuba, Japan, he has been since 2005 with the Friedrich Schiller University of Jena, Jena, Germany, first as a research assistant and later as a Junior Professor. In 2013 he was appointed full professor at the Karlsruhe Institute of Technology, Karlsruhe, Germany. There, he is heading groups at the Institute of Theoretical Solid State Physics and the Institute of Nanotechnology. He works on many aspects in the context of theoretical and computational nano-optics such as nanostructured pho-tonic materials, plasmonics, scattering theory, integrated photonics, quantum optics, and non-linear photonics. Carsten Rockstuhl is a fellow of the Optical Society of America. He serves the community as an editor with multiple journals, e.g., currently as Deputy Editor with Optics Letters. Moreover, he is the coordinate of the EUPROMETA, a doctoral school on Metamate-rials, and is the organizer or co-organizer of various conferences. He is a member of the Karlsruhe School of Optics & Photonics, where he currently acts as the dean of study.
Computational Nanophotonics explores the interaction of light with nanostructured materials by numerical means. It does so out of intellectual curiosity to explore novel phenomena. For a long time, the development of various numerical methods to solve Maxwell’s equations has been the focus of interest. Nowadays, challenges and opportunities often derive from the in-terplay with other scientific domains and technological developments. A canonical example would be 3D additive manufacturing technology based on laser lithography. It has been estab-lished to structure materials in voxels with the smallest length of only 100 nm, while the total material may stretch across millimeters or even centimeters. Each of these voxels is a degree of freedom that can or cannot contain material. A challenge is to provide blueprints for material distributions to serve specific applications. Another example would be the field of multi-scale and multi-physics modeling, where the properties of a macroscopic photonic device are de-rived from a quantum-mechanical analysis of its very primary constituents. A similar ability is also important when explaining the circular dichroism from molecules coupled to dedicated cavities that preserve the helicity of light and strongly enhance the field. In this talk, I will give an overview of these developments.

Wolfgang P. Schleich is engaged in research on quantum optics ranging from the foundations of quantum physics via tests of general relativity with light and cold atoms to number theory.
He was educated at the Ludwig Maximilians-Universität (LMU) in Munich and studied with Marlan O. Scully at the University of New Mexico, Albuquerque, and the Max-Planck Institute for Quantum Optics, Garching. Moreover, he was also a post doctoral fellow with John Archi-bald Wheeler at the University of Texas at Austin.
Professor Schleich is a member of several national and international academies and has re-ceived numerous prizes and honors for his scientific work such as the Gottfried Wilhelm Leib-niz Prize, the Max Planck Research Award, and the Willis E. Lamb Award for Laser Science and Quantum Optics, and the Herbert-Walther Prize. He is also a Faculty Fellow at the Hagler Institute for Advanced Study at Texas A&M University.
His textbook, Quantum Optics in Phase Space, has been translated into Russian and a Chinese edition was published in 2010.
The one-atom maser of Herbert Walther has ushered in a new era in quantum optics and paved the way to quantum information science. In this talk we focus on three quantum phe-nomena motivated by the seminal work of Herbert Walther: The Quantum FEL, cold atoms in space and the connection between analytic continuation in complex analysis and entangle-ment in quantum mechanics illuminated by the Riemann zeta function ζ. The key ingredient of the three examples is the elementary interaction between light and matter that is also at the very heart of the one-atom maser.
The quantum regime of the free-electron laser (FEL) emerges when the discreteness of the momentum of the electron plays a dominant role in the interaction with the laser and the wiggler field. We discuss the quantum properties of the radiation which share features of the one-atom maser.
We summarize our activities on the interface between quantum and gravity and review exper-iments on Bose-Einstein condensates in the drop tower in Bremen, the MAIUS rocket, and on the International Space Station.
We present a quantum mechanical system which when measured appropriately yields ζ. For its representation in terms of a Dirichlet series interference suffices to obtain ζ. However, in order to create ζ along the critical line where the non-trivial zeros are located we need two entangled quantum systems in complete analogy to the interaction of the atom and the cavity field in the one-atom maser.

Prof Silvia Vignolini studied Physics at the University of Florence, Italy. In 2009, she was awarded a PhD in Solid State Physics at the European Laboratory for non-Linear Spectrosco-py and the Physics Department at the University of Florence. In 2010, she moved to Cambridge as a post-doctoral research associate working in the Cavendish Laboratory and the Plant Science Department. In 2013, she started her independent research becoming a BBSRC David Philip Fellow. Dr. Vignolini is currently an Professor at the University of Cam-bridge in Sustainability and Bio-inspired materials. Her research interest lies at the interface of chemistry, soft-matter physics, optics, and biology. In particular, her research focuses on the study of how natural materials (like cellulose) are assembled into complex architectures within living organisms and how the such materials can be exploited to fabricate a novel class of photonic pigments.
The most brilliant colours in nature are obtained by structuring transparent materials on the scale of the wavelength of visible light. By designing the dimensions of such nanostructures, it is possible to achieve extremely intense colourations over the entire visible spectrum without using pigments or colorants. Colour obtained through structure, namely structural colour, is widespread in the animal and plant kingdom . Such natural photonic nanostructures are generally synthesised in ambient conditions using a limited range of biopolymers. Given these limitations, an amazing range of optical structures exists: from very ordered photonic structures , to partially disordered , to completely random ones .
In this seminar, I will introduce some striking example of natural photonic structures [2-4] and share some insight on their development. Then I will review our recent advances to fabricate bio-mimetic photonic structures using the same material as nature. Developing biomimetic structures with cellulose enables us to fabricate novel photonic materials using low cost polymers in ambient conditions [6-7]. Importantly, it also allows us to understand the biological processes at work during the growth of these structures in plants.
