häviökoherenssi
Häviökoherenssi, known in English as lossy decoherence, is a phenomenon in quantum mechanics that describes the process where a quantum system loses its coherence due to interactions with its environment. Unlike standard decoherence, which focuses on the loss of quantum superposition, häviökoherenssi specifically refers to the degradation of the system's ability to maintain a coherent quantum state when there's an irreversible exchange of energy or particles with the environment. This exchange leads to a net loss of information from the system into the environment, effectively "dissipating" quantum properties.
The term is particularly relevant in contexts involving energy transfer, such as in quantum thermodynamics or
