Ghalia Dhaoui came to EPFL from her home in Tunisia to do a bachelor’s in microengineering. Next spring, she will graduate from the first ever class of the EPFL Master’s program in Quantum Science and Engineering, where she specializes in quantum hardware, works in the Hybrid Photonics Laboratory, and is a student assistant for the Center for Quantum Science and Engineering (QSE).
How did youfirst become interested in science and quantum?
During the COVID-19 pandemic, I became deeply intrigued by quantum science through YouTube. This fascination led me to delve into complex subjects such as quantum teleportation, entanglement, quantum key distribution, and qubits by engaging in online courses and extensive reading.
A year later, I joined Professor Charbon’s Advanced Quantum Architecture Laboratory for a summer internship where I worked on Single-Photon Avalanche Diodes (SPADs) and got hands-on experience in managing optical and electrical setups, further enhancing my technical expertise.
That same year, EPFL introduced its new master’s program in quantum science and engineering, and I seized the opportunity to advance my studies and contribute to innovative research in this cutting-edge field.
What do you see as the most exciting part about being in the quantum field?
With a background in microengineering, I already had experience in physics, electronics, microfabrication, and programming. Transitioning to quantum hardware engineering has allowed me to apply these versatile skills to specialized areas like quantum sensing and communication. What excites me most about this field is the constant balance between reducing noise, loss, and uncertainty while enhancing coherence and efficiency. This challenge drives me to seek new platforms, innovative materials, advanced electronics, and precise microfabrication techniques, continuously expanding my knowledge in material science, physics, and electronics.
What has been the most rewarding part of being in the EPFL QSE Master’s?
The program has profoundly shaped both my personal and professional development. I’ve been able to benefit from highly-skilled professors and well-equipped and numerous laboratories. There is also a vibrant community in quantum here, thanks in part to the QSE Center, which organizes talks by leading researchers from academia and industry. Through dedicated mentorship from experts, access to advanced resources, and being part of this supportive community, I have acquired the knowledge, skills, and confidence needed to make significant contributions to the field. Additionally, the numerous networking events have allowed me to find opportunities for summer and industrial internships. And the newly established Quantum Engineering Team brings together master’s students who collaborate to achieve their goals and expand their professional networks.
And the most challenging?
Working in the hardware field often presents unexpected challenges, whether during measurements or microfabrication processes. However, these unforeseen problems encourage you to constantly ask why things happen, pushing you to expand your knowledge and enhance your problem-solving abilities. This continuous questioning not only increases your understanding but also strengthens your curiosity and patience, which are essential for overcoming complex technical issues.
When you’re not studying and working in the labs, what do you like to do for fun?
I enjoy staying active through fitness, tennis, and paddleboard. Cooking is a passion of mine, and I love preparing delicious meals. I also enjoy traveling, which allows me to explore new places and cultures. Spending time with friends is important to me, and I often return to Tunisia to visit my family and enjoy the beautiful weather. Additionally, I have a strong love for reading, especially science books, which keeps my curiosity alive.
