Your computer or phone wouldn't be all that useful if it couldn't communicate with other devices or if that communication wasn’t secure. The same goes for future quantum devices! By connecting many quantum computers and sensors together–similar to how “the cloud” connects our devices now–they will become all the more powerful and useful.
But connecting quantum devices is easier said than done. This is because, unlike the information we send today over cables and airwaves, the quantum information (qubits) we need to send between quantum devices is super-fragile. If the qubits interact with anything along the way to their destination they can be altered. Even the metal that makes up a regular electrical cable will change the state of a qubit as it travels down the wire. This means that we have to develop new ways to transmit and receive quantum information. It also means we can tell if someone is listening to our quantum communications because any eavesdropper will alter our qubits!
