I am a physicist, working in optical instrumentation and a photographer in my spare time.

Currently, I’m a Master’s student in Physics at University of São Paulo, where I graduated in Physics with a minor in Optics and Photonics (2019-2022). My research relies on laser development, emphasizing in high-repetition solid-state femtosecond lasers at Optics and Photonics Research Center (CEPOF).

I’m part of the organization of the Integrated Week of the São Carlos Institute of Physics - SIFSC, participate in the USP IFSC OPTICA Student Chapter and of the IFSC-USP SPIE Chapter.

I have a keen interest in optical instrumentation research spanning diverse applications, ranging from imaging to optical analysis, as well as in the development and application of femtosecond lasers for studies in nonlinear optics, laser-tissue interactions, and micromachining. I also possess photography expertise, encompassing both digital and analog photography, and covering a wide spectrum of subjects, including artistic photography and documenting physics experiments.

The Elitzur-Vaidman bomb testing problem is a thought experiment in quantum mechanics that explores the concepts of quantum superposition and entanglement. The problem creates a scenario where a bomb is activated by absorbing a single photon and suggests testing that it works without exploding it, so that classically, it is impossible to know if the bomb works without disturbing the system. Therefore, an interferometer with two arms and two outputs is proposed, mounted in such a way that only one of them has positive interference. However, when placing a pump that works in one of the arms, the interference pattern breaks down, and it can be inferred that the pump works without interacting with it. In this work, a methodology is adopted that combines computational simulations and a simple experimental proposal to investigate the concept of interaction-free measurements. The IBM quantum cloud programming language (Qiskit Runtime) is utilized to simulate the experiments, and an experimental approach is proposed that uses simple laser sources to qualitatively test the theory, offering a practical perspective for developing an understanding of quantum concepts.
