Chapter 2 Foundations I: States and Ensembles
... phase is physically irrelevant. A qubit is a state in a two-dimensional Hilbert space that can take any value of the form eq. (2.11). We can perform a measurement that projects the qubit onto the basis {|0i, |1i}. Then we will obtain the outcome |0i with probability |a|2, and the outcome |1i with pr ...

... but were so confused that there was little basis for progress, they created quantum mechanics in three tumultuous years. They were troubled by what they were doing and in some cases distressed by what they had done. The unique situation of this crucial yet elusive theory is perhaps best summarized b ...
