The research aims to verify the operation and security of the BB84 quantum protocol, as well as to understand the historical background that, as a whole, has led to this level of development in cryptography. It uses a simulation with photons to check the security of the protocol.

Study of Tabby’s Star (KIC 8462852) using Python’s Lightkurve to analyze photometric data from Kepler satellite telescope. Key steps include downloading and visualizing light curves, studying dips via Fourier transforms, and detecting periodicities. This approach aids in exploring anomalies like dust or exoplanet transits.

An interactive web tool demonstrating quantum computing principles have been created. It uses 3D Bloch Sphere visualization with Three.js to simulate photonic qubits. Users can apply quantum gates (Hadamard, Pauli-X, Pauli-Z), observe state transitions, and measure qubit probabilities. Educational platform simplifying quantum mechanics concepts for researchers and students.

This work focuses on the transmission electron microscope (TEM), that uses a beam of accelerated electrons to go through a very thin sample and generate images with atomic resolution. We will analyze its operation and its scientific applications, such as the diagnostics and material characterization of it.

This study talks about the star life cycle, looking to understand how scientists study the stellar composition, based on the stelar decomposition of the white light spectrum and spectroscopy. We also have built a spectroscope to demonstrate the research in a practical way with flame experiment.

My project consists of utilising different light bulbs that produce different wavelengths of light in order to see how well a solar panel absorbs them and what the ratio of efficiency of absorption is. My method will simply consist of shining these lights towards the solar panel and measuring the power generated compared to the power that is being used by the light bulb. The results show that the efficiency is still very low and there is still much more room for improvement.

The paper focuses on studying quantum cryptography, which promises to protect with 100% efficiency from quantum computers. It performs a classical simulation of the BB84 protocol of quantum cryptography, showing how it works. The conclusion shows some lack of effectiveness in certain areas, which can be (or not) solved in the future.

The dissertation explores whether experimental physics is accessible to all students. The hypothesis is that fundamental physics laws can be verified through simple experiments with accessible materials. Two experiments were conducted: determining Planck’s constant via LEDs and building a spectrometer to observe emission spectra. Both experiments yielded expected results, confirming the hypothesis that experimental physics can be learned through simple, affordable methods.

Have you ever wondered, what if we could see music? Our project, Sonor-Art, was born with the intention of developing the relationship between “deaf” people with music. For that reason we constructed our project with materials that were completely recycled and reused with the objective of being aligned with the 2030 Agenda. Moreover, Sonor-Art has allowed us to study various very interesting physical and mathematical phenomena through experimentation (Snell’s law, standing waves, resonance, etc.). As for the construction, is very simple, there is a sound cavity with a membrane that has a mirror attached, as well as PVC pipes and a source of light that “emits infrared” lights. Furthermore, it has a very simple functioning, the beam of light reflects in the screen due to the reflection in the mirror that vibrates thanks to the sound waves produced. Consequently, the point in the screen moves creating different figures, this way, sound becomes visible.
