The University of Barcelona in Spain has developed experimental equipment to help undergraduate students learn about complex quantum physics. The equipment, detailed in a paper published in the journal EPJ Quantum Technology, aims to prepare students for research in quantum technologies, a field that is experiencing rapid growth. UNESCO has designated 2025 as the International Year of Quantum Science and Technology, highlighting the importance of this area of study.
One aspect of quantum mechanics explored by the equipment is quantum entanglement, a phenomenon where particles affect each other across space instantaneously. This concept was famously debated by Einstein and others, leading to the development of Bell inequalities as a way to test the boundaries of quantum entanglement.
The new equipment allows students to directly measure quantum entanglement by preparing different entangled states of photons. The team behind the project believes that hands-on experience will help students better understand this complex phenomenon. The equipment is designed to be user-friendly, with detectors assembled to optical fibers to simplify the experiment process.
The equipment is already in use in classrooms at the University of Barcelona and is designed to be accessible for teaching in a variety of settings. By providing students with the tools to explore quantum entanglement firsthand, the researchers hope to inspire a new generation of scientists in the field of quantum technology.
