CLEO Keynote

Practical quantum communication and processing

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.

CLEO Keynote

Nonlinear THz spectroscopy to study the solvent dynamics in water

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.

CLEO/Europe-EQEC Keynote

High-field physics in nanostructures

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.

CLEO/Europe-EQEC Keynote

Advances towards deep-UV light emitting diode technologies

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.

CLEO/Europe-EQEC Keynote

Quantum Multiplexed Networks

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.

Challenges and Opportunities for Computational Nanophotonics

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.

CLEO/Europe-EQEC Keynote

Cavity QED, Cold Atoms and the Riemann Zeta Function

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.

CLEO Keynote

Biomimetic colour engineering form nature to applications

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 [1]. 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 [2], to partially disordered [3], to completely random ones [4].

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.
