Minimising back action in quantum many-body systems
Quantum simulation offers the possibility to study notorious physical phenomena in many-body quantum systems. When an observable system is measured, the detector making the measurement can also affect the observed system under a perturbing effect, breaking its quantum coherence. This back action effect has important consequences for the measurement process. Funded by the Marie Skłodowska-Curie Actions programme, the QuProbe project aims to increase understanding of how back action affects many-body quantum systems. To this end, it will develop and experimentally apply proper quantum probes for many-body quantum systems. QuProbe will combine existing expertise with techniques borrowed from the fields of ultracold atoms, quantum optics and biological imaging.
