Which outcome limits quantum computing fidelity due to qubit entanglement?

💡 Explanation

Environmental decoherence introduces unwanted interactions because random fluctuations disrupt the entanglement linking qubits, therefore fidelity drops, rather than remaining coherent like continuous quantum computation allows in ideal setups.
