Deutsch argues that the solution maximizing von Neumann entropy (a measure of how scrambled or mixed the information in the qubit is) is the most relevant. In this case, the qubit becomes a mix of starting at 0 and ending at 1, or vice versa. Deutsch's interpretation, which can align with the many-worlds view of quantum mechanics, avoids paradoxes because the qubit travels to a different parallel universe after interacting with the CTC.
