Накратко на български

Взаимодействията между фотони и квантови излъчватели, като квантови точки, се анализират чрез нови методи за измерване на многофотонни корелации. Това помага за по-доброто разбиране на квантовите интерфейси и създаването на устройства за обработка на квантова информация.

Multi-photon probing of complex open quantum systems

Photon-based quantum technologies are a promising platform for processing quantum information, because it combines the resilience of the photon with simple and powerful tools for its manipulation. A key requirement towards this goal is building and understanding deterministic light-matter quantum interfaces, where photons and quantum emitters can interact strongly at the level of few quanta. This enables the engineering of strong photon-photon interactions mediated by the emitters and the construction of two- or multi-photon quantum photonic devices for creating quantum superpositions and entanglement between photons. Modern nanophotonic and nanofabrication techniques allow for the control of these quantum light-matter interactions in many labs around the world, for instance, with quantum dot or atomic emitters coupled to nanophotonic waveguides or ---in the microwave regime---with superconducting qubits coupled to transmission lines. Nevertheless, the characterization of those interactions is typically limited to measure single-photon transmission, second order correlations, or pump-probe experiments, which give only partial information about the generated photon quantum correlations and the effect of the nanophotonic environment. The overall objective of this project was to develop more sophisticated multi-photon probing protocols to enable a complete characterization of photon-photon correlations induced by complex quantum emitters, including realistic conditions of noise and dissipation due to the nanophotonic environment. In addition, these techniques should be simple enough to be implemented with standard optical control and measurement tools, such as monochromatic coherent input states and homodyne or intensity detection methods. The action concluded with the theoretical development of such a protocol and with its experimental test in collaboration with the group of P. Lodahl at the Niels Bohr Institute, Copenhagen.

Цел на проекта

In this Marie Sklodowska-Curie action we explore the prospects of controlled multi-photon scattering processes as a probe of the nonlinear interactions and the dynamics of complex open quantum systems. The core of the project builds around the development of novel analytical and numerical tools to model complex scattering processes under correlated noise and dissipation. The project is thus mainly theoretical, but it is also interdisciplinary and focuses on problems and setups that admit immediate experimental implementations in a variety of state-of-the-art platforms, such as superconducting qubits coupled to microwave photons in transmission lines or quantum emitters coupled to photonic crystal waveguides. Moreover, the techniques and ideas that we will develop should be essential for the understanding and control of light-matter interactions in the multi-photon regime, as well as for the engineering and modelling of new and robust photon-based quantum technologies.
