    Quantum computing and quantum communication require a different way of thinking about handling information. Not only are quantum states extremely delicate, but you can't copy a quantum state. To put it in perspective. If I want to send a qubit from a lab in Europe to somewhere in New York, that qubit has to make it all the way by itself-you can't read and replace it along the way. To get around this limitation, you have to make use of quantum mechanics: teleporting quantum states from one place to another.
    To do that in a flexible way that allows computation, you need to store...
