Which consequence results when entangled quantum dot qubits decohere?

💡 Explanation

Decoherence corrupts quantum states because interaction with the environment introduces random phase changes— dephasing— leading to loss of fidelity therefore diminishing entanglement, rather than stabilizing superposition, improving gate accuracy, or directly affecting the qubit energy gap.
