dekoherenciával

Dekoherencia refers to the process by which a quantum system loses its quantum properties, such as superposition and entanglement, and begins to behave like a classical system. This loss of quantum coherence is caused by interactions with the surrounding environment. Imagine a quantum particle existing in multiple states simultaneously; dekoherencia is what causes it to settle into a single, definite state.

The environment acts as a measurement device, continuously probing the quantum system. Even a seemingly insignificant interaction, like a stray photon or vibration, can lead to dekoherencia. The more complex the environment and the longer the system interacts with it, the faster dekoherencia occurs. This is why maintaining quantum states for extended periods is a significant challenge in quantum computing and other quantum technologies.

Dekoherencia is a crucial concept for understanding the transition from the quantum realm to the classical world we experience. While quantum mechanics describes phenomena at the atomic and subatomic levels, our everyday observations are governed by classical physics. Dekoherencia provides a mechanism for this apparent transition, explaining why we don't observe macroscopic objects in superposition. It's a fundamental process that limits the fragility of quantum information and plays a vital role in the interpretation of quantum mechanics.
