kokonaisdekoherenssia

Kokonaisdekoherenssia, often translated as total decoherence, refers to a phenomenon in quantum mechanics where a quantum system loses all its quantum properties and behaves like a classical system. This loss of quantum coherence occurs due to interactions with its environment. Quantum systems are characterized by superposition, where a particle can exist in multiple states simultaneously, and entanglement, where multiple particles are linked in such a way that their fates are intertwined.

Decoherence is a process by which these delicate quantum states are destroyed. When a quantum system interacts with its surroundings, which are inherently macroscopic and complex, information about the quantum state leaks into the environment. This interaction effectively "measures" the quantum system, forcing it into a definite classical state. Total decoherence signifies the complete erasure of any quantum correlations, leaving behind a system that can be described by classical physics.

The environment can include anything from stray photons and air molecules to the very apparatus used to observe the quantum system. The more entangled a system becomes with its environment, the more pronounced the decoherence effect. This process is a significant hurdle in the development of quantum technologies, such as quantum computers, as it can lead to errors and the loss of computational advantage. Understanding and mitigating decoherence is therefore a crucial area of research in quantum physics.
