What are the fundamental limits to our ability to measure physical phenomena? How can we measure quantum behavior in macroscopic objects? How can we control the quantum state of a specific device to perform an experiment with greater precision? Combining quantum information theory with experimental physics aims to investigate such questions. Through the quantum optics we perform small experiments, using low energies, aiming on study potentially relevant fundamental phenomena for high energy physics. We are currently developing an opto-mechanical sensor for measuring forces and displacements. This device will work as a laboratory for the experimental study of quantum metrology, allowing also the study of macroscopic quantum phenomena. The experiment will also be able to impose limits on the existence of scalar and pseudo-scalar particles in addition to the standard model, whose existence would lead to a fifth fundamental interaction of the Yukawa type.
