Tutors: Morgan Mitchell, Daniel BenedictoFaraday rotation measurements (FRM) are highly valuable due to their potential to behave as quantum non-destructive measurements under certain conditions. Moreover, applying FRM to Bose-Einstein condensates (BEC) offers significant insights into the magnetic properties, dynamics, and quantum phenomena of the condensate. To optimize FRM on a BEC, we have implemented an optical cavity that maximizes the interaction between atoms and light. In this work we present a frequency locking system for a 780nm probe laser implementing a Maximum Search Algorithm in a microcontroller Arduino UNO. The implementation of this system has yielded promising results, reducing the noise after the cavity by ∼ 20dB compared to the system without the algorithm. Consequently, we can approach the shot noise limit more closely, stabilizing the set-up for the Faraday rotation measurements.31 p.application/pdfengcc-by-nc-nd (c) Méndez, 2023http://creativecommons.org/licenses/by-nc-nd/3.0/es/Mesura en mecànica quànticaTreballs de fi de màsterMeasurement in quantum mechanicsMaster's thesisinfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/openAccess
