Well that is a broad (and maybe unfair) statement.

Quantum Key Distribution (QKD) solves an applied problem of secure key
distribution. It may not be able to ensure "unconditional" secrecy
during key exchange, but it can detect any eavesdropping. Once
eavesdropping is detected, the key can be discarded.
