Small BBO Polarization Entanglement Source Teaching System
The compact BBO polarization-entanglement source system, based on the spontaneous parametric down-conversion process in a nonlinear crystal, enables the generation, collection, and characterization of entangled photon pairs. This system not only draws upon a wide range of theoretical knowledge—including geometrical optics, polarization optics, nonlinear optics, and quantum mechanics—but also integrates various experimental techniques. It holds great promise for fundamental research in quantum information, experimental teaching, and public outreach in quantum science. With its compact design, the system features a partitioned layout that separates the entanglement-generation module from the characterization module, making it particularly user-friendly and easy to learn and operate for beginners.

Quantum Magnetic Precision Measurement Experimental System
The quantum magnetic precision measurement experimental system is a highly sensitive magnetic field measurement device that leverages the quantum properties of atoms. Its operating principle relies on the interaction between light and atoms (such as optical pumping and magnetic resonance) to detect weak magnetic field signals. The core principle is the modulation of atomic energy levels by magnetic fields (e.g., the Zeeman effect), and magnetic field measurements are achieved by using lasers to detect changes in the atomic spin states.
