Which constraint impacts quantum computing advantage when qubits decohere upon interacting?

💡 Explanation

Quantum gate fidelity decays due to increasing decoherence destroying superposition, causing computational errors. Error correction cannot isolate entangled qubits; thus, it reduces advantage because entanglement is necessary for quantum algorithms, rather than topological protection which addresses noise directly.
