Which security risk arises when implementing quantum key distribution (QKD) based on entangled photons?

💡 Explanation

Leakage occurs because repeaters boost signal range by performing measurements and re-encoding states. The measurement breaks the quantum entanglement, therefore allowing information leakage at the repeater node rather than securing it completely.
