Quantum batteries can charge faster and store energy longer than conventional ones. But they are hindered by the environment — energy leaks out like water from a leaky bucket. Physicists have found a way: use "dark states" that make the battery invisible to losses. This is a path to everlasting quantum accumulators.
🎯 Interestingly, "dark states" already save energy in nature: some photosynthesis processes use similar mechanisms to transfer sunlight deep into cells without losses.
