Ask an organization who owns cybersecurity, cloud infrastructure, data privacy, or regulatory compliance, and chances are you will get a specific answer quickly.

Ask who owns quantum readiness, and the answer is often much less clear.

That ambiguity matters.

Preparing for the Quantum Era is frequently treated as a cybersecurity problem. That makes sense at first. Much of the immediate concern revolves around cryptography: the algorithms protecting sensitive information, communications, identities, transactions, and digital infrastructure.

But replacing vulnerable cryptography across a complex organization goes beyond security. It touches technology, data, hardware, procurement, vendors, budgets, compliance, business operations, and long-term risk.

Which creates a surprisingly difficult question: Who is actually responsible for making sure the organization is ready?

The problem crosses the org chart

In my previous articles, I described quantum readiness through three clocks: the Data Clock, the Migration Clock, and the Quantum Clock. But no single department naturally owns all three.

The Data Clock measures how long information created today needs to remain protected. The CISO may understand the security exposure, but may not know how long every category of business information needs to remain confidential. Business leaders, legal teams, data owners, and compliance functions may have important parts of that answer.

The Migration Clock measures how long an organization may need to discover its cryptographic dependencies,........
