YGS-2 Portable Michelson Demonstrator / Equal Inclination and Equal Thickness Interference Demonstrator

The Michelson interferometer is a crucial instrument in physics—it not only confirmed Einstein’s postulate of the constancy of the speed of light, but also demonstrated that light can propagate and exhibit interference without requiring a medium—meaning that the so-called "ether," once thought to permeate space, does not exist. Yet, this groundbreaking discovery simultaneously gave rise to a lingering puzzle in physics (often referred to as "a single dark cloud"): if there’s no ether—no medium—how exactly does light travel? And more specifically, how does light produce interference in the first place? As Albert Einstein once remarked, "I’ve always regarded Michelson as an artist among scientists; his greatest joy seemed to stem from the sheer elegance of the experiment itself and the masterful precision of the methods he employed." To scientists, the Michelson interferometer is not just a scientific tool—it’s also a remarkable work of art. For both functionality and aesthetic appeal, the LGS-2 portable Michelson product comes encased in a sleek, transparent acrylic display box, offering dual protection: it shields the instrument from dust while transforming it into a captivating piece of art. After all, this device aims to balance practical utility with artistic value.

DF-LZ500 Superconducting Quantum Computer Large-Scale Teaching Equipment for High and Advanced Levels

A quantum computer is a machine capable of performing quantum computing, leveraging the principles of quantum mechanics to carry out mathematical and logical operations, as well as process and store information. Theoretically, it is a physical system that uses quantum bits (qubits) as its fundamental storage units, with quantum dynamical evolution forming the basis for information computation. Currently, the main technological approaches can be categorized into six types: superconducting, ion-trap, photonic quantum, neutral atoms, silicon spin, and topological.
