One can of course have other operations, such as adding a quantum system and discarding part of a system. In general, one can use arbitrary sequence of the above operations to an existing system A, su ...

But, for a quantuln system, a single measurement of any observable A yields one of the eigenvalues of A as the outcome, and collapses the state of ...

... We mentioned before that measuring collapses the state, but what if we could take our quantum state and duplicate it? How would this look like? α |0� + β |1� → (α |0� + β |1�)(α |0� + β |1�) = α2 |00� + αβ |01� + αβ |10� + β 2 |11� Therefore we just need to find some unitary transformation to perform ...
