Area A: Quantum cooperativity induced by measurement processes

Summary of the area

The common denominator of all projects in area A is to understand and characterize the role of the quantum measurement in determining quantum cooperative dynamics. At its core is the investigation of how measurement and measurement back action establish quantum correlations, and how the emerging correlated states are robust against perturbations by the environment. The range of quantum platforms employed for the experiments in area A display a rich diversity, i.e., trapped ions, color centers in diamond, organic molecules, coherent electrons, spin ensembles and x-ray photons.

Projects

• A01 – Cooperative light emission and spatio-temporal photon correlations from trapped ion arrays
• A02 – Generation of photonic cluster states from color center-cavity systems
• A03 – Correlated x-ray photons for incoherent diffraction imaging
• A04 – Spatio-temporal correlations of electrons emitted from femtosecond laserdriven needle sources
• A05 – Cooperative effects of a defined number of organic molecules embedded in a dielectric antenna
• A06 – Tailor-made beyond-one-excitation quantum states for quantum information and communication
