← ScienceWhich quantum computing consequence results when entangled qubits decohere before a computation completes?
A)Output error rate experiences increase.✓
B)Qubit superposition phase becomes fixed.
C)Entanglement swapping stops functioning.
D)Entangled state initialization fails entirely.
💡 Explanation
When entangled qubits decohere prematurely during a quantum computation, environmental interactions disrupt their superposition, collapsing the waveform because precise phase relationships are lost, inducing computational errors. Therefore output error rate increase results, rather than phase locking, swapping failure, or initialisation failure, because these depend other conditions.
