Which risk increases when the width of the insulating aluminum oxide layer in a Josephson junction shrinks below a few nanometers?

💡 Explanation

Increased `quantum mechanical tunneling` becomes problematic because, at small dimensions electrons pass through the insulator even without sufficient voltage. Therefore, unintended current can flow, rather than proper switching behavior required for quantum computation.
