Quantum computation and entanglement

  1. Sep 14, 2014 #1
    Hi everyone
    I am working on entanglement between an atomic system and its spontaneous emission but I don't know how to connect this kind of entanglement with quantum computation, I have read in different articles that entanglement is somehow essential in applications like quantum communication & computation,so how is it helpful in quantum computation to entangle atomic system with its spontaneous emission?

    I don't know enough about quantum computing hardware to know the answer. However, in general, just because entanglement is present doesn't mean we can use it.

    I don't know whether the definition of entanglement is fully settled, but these discussions seem reasonable to me. They give examples of entanglement that we cannot take advantage of if our apparatus is limited.
