IonQ 撰文提醒，2029 年后量子密码（PQC）升级对 2027 年已被截存的流量无济于事，“先截取后解密”（HNDL）意味着等待并非中立选择。企业无需等待整体基础设施更换，可优先保护流量汇聚的高价值 WAN 和数据中心路径，将密钥分发与物理传输硬件解耦，并把量子安全密钥注入现有加密设备，避免让最慢的依赖项决定风险时间线。

A 2029 post-quantum cryptography (#PQC) upgrade does nothing for traffic harvested in 2027.
Harvest-now-decrypt-later (HNDL) means waiting isn’t neutral. You don't have to wait for full infrastructure refreshes to protect your most sensitive corridors.
🔸 Prioritize high-value WAN and data-center paths where traffic aggregates.
🔸 Decouple key delivery from the physical transport hardware.
🔸 Feed quantum-safe keys into your existing encryptors today.
Stop letting the slowest dependency dictate your risk timeline.
