The aim of this workshop is to contribute to the understanding of key tools in quantum information – such as entanglement – within the framework of relativistic quantum field theory (QFT). While quantum information typically involves finite-dimensional Hilbert spaces, QFT and related approaches to quantum gravity, must deal with systems featuring infinitely many degrees of freedom, posing additional conceptual and technical challenges, while at the same time offering potentially new and interesting features. The workshop will bring together researchers from both fields to foster collaboration, extend quantum information tools to relativistic QFT, and explore new joint research directions.

Sensor systems exhibit extraordinary sensitivity for detecting physical, chemical, and biological entities at the micro/nanoscale. The detection and analysis of molecules on miniature devices with many possible applications in health, environment, analysis, and security is particularly exciting. A new class of label-free micro and nanosensors is starting to emerge, allowing us to observe dynamic processes at the single molecule level directly, with unprecedented spatial- and temporal resolution and without significantly affecting the natural and functional movements of the molecules. Micro- and nanosensors by virtue of their small interaction length probe molecules over a dynamic range often inaccessible by other techniques. Their small size enables an exceedingly high sensitivity, and the application of quantum optical measurement techniques can allow us to approach or surpass classical limits of detection. Advances in optical and electrical measurement methodology, laser interferometry, quantum optics, micro/nanofluidics, control of molecules and reactions at the nanoscale, DNA origami/synthetic molecular machines, in-vivo and wearable sensing materials, all contribute to the rapid progress of the field of Single Molecule Sensors and NanoSystems. It is this convergence of previously often disparate fields that is accelerating the advancements in micro and nano-sensing.

Confining electromagnetic fields in cavities has emerged as an important new tool to create and control complex quantum systems. The first experimental realizations were based on ultracold atoms and on semiconductor heterostructures with the generation of polaritonic quantum fluids of light. Since then, efforts on applications in quantum technologies are ongoing, where extremely well controlled atomic or ionic building blocks are assembled to generate highly entangled states of matter.
