← ScienceWhich consequence results when reading one qubit's state from entangled qubits in a trapped-ion quantum computer?
A)Destroys superposition in measured qubit✓
B)Entanglement is unaffected by measurement
C)Induces measurement error in remaining qubit
D)Increases fidelity due to wavefunction collapse
💡 Explanation
Decoherence occurs because measuring a qubit forces it into a definite state, destroying its superposition via wavefunction collapse; therefore the linked, entangled qubit immediately assumes the corresponding correlated state, rather than remaining in a probabalistic superposition.
