> Abstract:
> 
> The size and mass of physical systems in which entangled states, number states and other non-classical states can be generated is growing. In the talk we will first review our experiments with macroscopic mechanical and atomic systems where measurements with sensitivity exceeding the standard quantum limits have been performed [1,2]. These experiments pave the road towards simultaneous detection of arbitrarily small perturbations in both position and momentum, usually referred to as trajectories without quantum uncertainties. Progress towards application of those ideas to gravitational wave detectors [3] will be reported. Another intriguing goal is generation of single excitations and superposition states of large objects. An experiment demonstrating evidence of generation of a single quantum excitation of motion of a millimeter size mechanical oscillator [4] will be discussed. Finally, our atomic platform for multi-particle quantum simulations will be introduced.
