Накратко на български
Взаимодействията между светлина и атоми в нанофотонни структури се изследват чрез използването на фотонни кристали. Това помага за намаляване на загубите на информация, което е важно за подобряване на квантовите компютри и паметта за данни.

Light-Atom Interactions in Nanophotonic Structures
Quantum science is now at the spotlight of both government and industry alike, as demonstrated by the amount of both public funding (through the European Quantum Flagship) and the news-worthy investment of private companies such as Google or Microsoft. While the future is promising, there are still many challenges ahead that must be overcome before society benefits fully from robust quantum technologies. In particular, in the context of quantum science, dissipation is a colossal problem. Losses curb our ability to realize controlled and efficient interactions between photons and atoms, which are essential for many technologies ranging from quantum information processing and quantum non-linear optics to metrology and imaging. Spontaneous emission - in which photons are first absorbed by atoms and then re-scattered into undesired channels - imposes a fundamental limit in the fidelities of many quantum applications, such as quantum memories and gates, key ingredients to realize protocols for controllable processing and storage of quantum information. Within this context, the overall objectives of LANTERN are: • To theoretically propose new techniques to manipulate atom-photon interactions that overcome major bottlenecks faced by current experiments to use atoms in quantum information processing and quantum simulation. • To guide state of the art experiments with realistic photonic crystal structures (dielectric structures with a spatially-varying refractive index that guide light) that can be used to induce low-dissipation, tunable, long-range interactions between atoms. • To understand the phenomenon of atomic collective dissipation and harness it to improve the performance of quantum information protocols.

Цел на проекта
In recent years, tremendous progress has been made to interface cold atoms with nano-photonic systems, with the motivation of scaling down and transferring ideas from macroscopic platforms, such as cavity QED in Fabry-Perot cavities. However, little attention has been devoted to identifying completely new paradigms for light-matter interactions, which take full advantage of the ability to control the dimensionality and dispersion of light in nanoscale optical structures. Within this context, LANTERN makes an ambitious attempt to theoretically propose new techniques to manipulate atom-photon interactions, to design realistic photonic crystal structures that are simultaneously capable of trapping atoms and realizing the desired physical phenomena, and to help guide state-of-the-art experiments in the field. The fellow will show how such structures can be used to induce strong and tunable long-range interactions between atoms, and to realize strong optical nonlinearities at the single-photon level that do not depend on the saturation of an atom. These approaches are expected to overcome major bottlenecks faced by current experiments to use atoms in quantum information processing and quantum simulation. The multidisciplinary perspective of this action will advance the state of the art in quantum optics, nanophotonics and atomic physics, and will lead to fruitful synergies between theoretical and experimental groups. During the outgoing phase of the grant, Ana Asenjo will join the Quantum Optics group lead by Prof. Kimble at Caltech, in the USA. In the return phase, she will team up with the Theoretical Quantum-Nano Photonics group lead by Prof. Chang at ICFO, in Spain.
