Quantum Coherence and Decoherence (scientific concepts)

Quantum coherence refers to the property of particles, like electrons or photons, to exist in multiple states simultaneously, creating a delicate "interference" pattern. Decoherence occurs when the environment interacts with these quantum systems, disturbing their delicate states and causing them to behave classically—losing their quantum properties. In simpler terms, coherence is the "quantum magic" that allows particles to be in multiple states at once, while decoherence is the process that destroys this magic, making particles act normally. Maintaining coherence is essential for developing quantum technologies like computers and sensors.
