← ScienceWhich consequence arises when spin entanglement collapses inside a quantum computing register?
A)Increased decoherence error rate✓
B)Decreased electron tunneling effects
C)Enhanced qubit state fidelity
D)Reduced computational complexity limits
💡 Explanation
Decoherence increases because entanglement collapse forces instantaneous wavefunction localization; rather than maintaining superposition, qubits prematurely decohere. Therefore register fidelity is reduced; this is an error, not enhancement or a complexity change.
