Random-Receiver Quantum Communication

We introduce the task of random-receiver quantum communication, in which a sender transmits message to receiver chosen from list n spatially separated parties. The choice is unknown sender, but known by parties, who coordinate their actions exchanging classical messages. In normal conditions, communication requires noiseless channel each receivers. contrast, we show that can take place through entanglement-breaking channels if order such controlled bit accessible measurements. Notably, this phenomenon cannot be mimicked allowing free between and any subset k<n
