Quantum mechanics is compatible with scenarios where the relative order between two events can be indefinite. Here we show that two independent instances of a noisy process can behave as a perfect quantum communication channel when used in a coherent superposition of two alternative orders. This phenomenon occurs even if the original process has zero capacity to transmit quantum infor... https://safeersappliancers.shop/product-category/neff-d85ibe1s0b-chimney-cooker-hood-a-energy-rating-black/
