Is it in a Quantum superposition, and then only in a mixed state when finding the reduced state of a qubit from an entanglement of multiple qubits?

SUMMARY
A qubit exists in a quantum superposition until a measurement is made, at which point it can be described as a mixed state if derived from an entangled system of multiple qubits. The discussion confirms that the transition from superposition to mixed state occurs during the process of obtaining the reduced state of a qubit. This distinction is crucial for understanding quantum mechanics and the behavior of qubits in quantum computing.
