← ScienceWhich outcome limits quantum computing speed when measuring entangled qubits?
A)Wave function state decoherence✓
B)Spontaneous parametric down-conversion
C)Critical magnetic field dissipation
D)Quantum superposition state tunneling
💡 Explanation
Wave function state decoherence degrades the quantum information due to interaction with the environment; environmental noise disturbs the entangled state and collapses wave functions. Therefore, decoherence limits computation speed rather than down-conversion influencing only photon entanglement and altering frequency.
