Each improvement in the sensitivity of gravitational wave detectors allows for the observation of even more distant events. This corresponds to an increase in the frequency with which they are detected, allowing researchers to study and investigate phenomena that were not previously accessible using regular telescopes. For this reason, gravitational wave observatories constantly undergo improvements aimed at boosting their sensitivity. We intend to work on the experimental implementation of such a system with the purpose of improving the sensitivity of gravitational wave detectors beyond the standard quantum limit. To achieve this goal, we seek to interact a mechanical oscillator with an atomic oscillator using entangled beams generated in an OPO. This is very similar to the teleportation of a state prepared in an atomic system. The Master's project associated with this one aims to carry out a teleportation protocol between systems that are resonant at different wavelengths. We intend with this internship to learn the techniques of interaction with atomic systems and implement them in a teleportation protocol involving such systems.
