Introduction to Quantum Information and Computation for Chemistry
... a measurement will collapse the state to either one of its component states |0 or |1, which is a widely observed phenomenon in quantum physics. Suppose we repetitively do the following: prepare a qubit in the same state α|0 + β|1 and then measure it with respect to the basis state {|0, |1}. Th ...
