With global governments having collectively pledged more than $38 billion in public funds for quantum technologies and $2.1 billion of new private capital flowing to quantum companies in 2022, quantum technologies, particularly quantum computers, are rapidly moving from the lab to the commercial marketplace.

By leveraging the principles of quantum mechanics, quantum computers have the potential to perform certain computations exponentially faster than classical computers.

On the opposite side of that coin, certain quantum technologies can strengthen existing encryption and power an estimated $30 billion quantum cybersecurity market by the end of the decade.

1) Begin inventorying cryptography systems that will be vulnerable to future quantum attacks2) Develop "Quantum IQ" across your organization by exploring the benefits and risks that quantum technologies will pose for your business3) Review the NIST post-quantum algorithms and create a strategy for cryptographic agility that will allow you to shift your systems to the final standards and protect your data with minimal disruption; and4) Identify partners established in the quantum ecosystem who can guide you through the transition to quantum-resilient cybersecurity while protecting data from both classical and quantum cyberattacks.

Cryptographic agility will provide organizations the freedom to assess and test quantum-leveraged cybersecurity solutions such as quantum-hardened keys and quantum key distribution as part of an "All of the above" approach to cybersecurity in the quantum age.

One of the benefits of quantum is that it is fundamentally unpredictable and applying the power of quantum computers to harden encryption key generation can protect sensitive encrypted data and communications against current and emerging threats.
