WHY DOES THE WORLD NEED TO TALK ABOUT QUANTUM NOW?
We are living in a time of major transition, where the classical world that has shaped civilization for thousands of years is beginning to be replaced by new principles derived from the quantum realm. Concepts such as quantum superposition-which states that a particle can exist in two states simultaneously-not only transform our understanding of reality but also open the door to a global technological, economic, and social revolution.
The date April 14, celebrated as World Quantum Day, is not merely symbolic. It represents a historic moment for civilization, marking the importance of quantum physics in reshaping the future. Yet behind this tremendous potential lies existential risks that must be deeply understood and addressed with cross-disciplinary global responsibility.
SUPERPOSITION: THE CORE OF THE INVISIBLE WORLD
1. Scientific Meaning
Superposition asserts that subatomic particles [electrons, photons, etc.] can exist in two states at once-two positions, two velocities, even two conditions of life and death [as illustrated in the Schrdinger's cat thought experiment].
2. Technological Applications
Superposition is the foundation for:
Quantum Computing: enables parallel processing of vast amounts of data.
Quantum Cryptography: unhackable communication systems.
Quantum Sensors: detect diseases, earthquake vibrations, and underground fields.
