Quantum Decoherence

In the quantum world, particles can exist in superpositions and entangled states. But when these particles interact with their environment—like air molecules or light—they lose their quantum properties. This process is called quantum decoherence.

You can think of decoherence like a delicate soap bubble that pops when touched. The quantum “weirdness” disappears, and the system starts to behave more like a classical object.

Decoherence explains why we don’t see quantum effects in our everyday lives and is a big challenge in building quantum computers, which need to stay “coherent” to work properly.
