Which consequence immediately arises in a CNOT logic gate implemented using weakly overlapping quantum dot wave functions?

A)Decreased quantum entanglement fidelity
B)Increased photon emission probability
C)Elevated operating temperature needed
D)Enhanced spin decoherence sensitivity

💡 Explanation

Decreased quantum entanglement fidelity results because **quantum decoherence** introduces errors when wave functions weakly overlap in implementing CNOT entangling gate architectures; therefore, the entanglement suffers, rather than other optical or thermal disturbances.
