Which constraint arises if two entangled qubits within a quantum computer's superconducting circuit decohere prematurely?

💡 Explanation

Reduced gate fidelity arises because decoherence destroys the superposition states required for entanglement, disrupting quantum algorithms. Therefore, the correlated calculations become unreliable rather than maintaining functionality under increased temperature or current loads like ordinary circuits.
