To address the question about the term for qubits that exist in multiple states simultaneously, we need to clarify the concepts provided in the answer options.

1. Entanglement - This refers to a phenomenon where quantum particles become correlated in such a way that the state of one particle cannot be described independently of the state of the other(s), even when the particles are separated by large distances.

2. Superposition - This is the principle that allows quantum bits (qubits) to exist in multiple states at the same time. In contrast to classical bits, which are either 0 or 1, qubits can be in a state that is a combination of both.

3. Quantum Parallelism - This concept relates to the ability of a quantum computer to perform many calculations at once, leveraging the properties of superposition.

4. Photonic Computing - This refers to the use of photons (light particles) to perform computations, which can also incorporate principles of quantum mechanics, but it is not specifically about the states of qubits.

In conclusion, the correct term for qubits existing in multiple states simultaneously is Superposition.
