An Introduction to Quantum Computation
... These two states are important in their own right. We denote them as |+i and |−i, respectively. For later use, we note that if we apply a Hadamard gate again, we will return to our original qubit. That is, H|+i = 0, and H|−i = 1. Notice that these two states have identical probabilities but differe ...

... 2nd example: magnetic moment of hyperons The neutral Λ0 lives τ = 0.26 ns. Its mass is mc2 = 1.1 GeV. When it is produced at Ekin = 400 GeV, its lifetime in the laboratory system is boosted to γτ = (Ekin /mc2)×0.26 ns ≈ 100 ns, and its mean flight length becomes cτ ≈ 30 m. The main decay mode is Λ0 ...

Then, we started introducing a classical state with LT = 1, and through local manipulations, we arrived at a new state with LT = 2. During the process, LR did not change, as expected.
