Quantum Cybersecurity Focus: ITI’s guide prioritizes post-quantum cryptography to protect against quantum decryption threats.
Global Collaboration: Advocates for international cooperation to standardize quantum cybersecurity measures.
Hybrid Strategies: Recommends combining PQC and quantum communications for resilient, risk-based security.
Quantum Cybersecurity’s Dual Nature
Quantum cybersecurity, as outlined in ITI’s Quantum Technology Policy Guide released on World Quantum Day, April 2025, represents a shift in how organizations safeguard data. The guide, published by the Information Technology Industry Council (ITI), addresses the opportunities and risks of quantum computing, communications, and sensing. Quantum technologies may promise accelerated drug discovery and secure communications but potentially could threaten existing encryption systems.
Policymakers, industry leaders, and academia must collaborate to navigate these complexities, ensuring innovation thrives while mitigating risks. Avoiding overly restrictive regulations stifiling progress, the guide emphasizes proactive policies to integrate quantum threats into existing security frameworks.
The ITI highlights quantum’s dual nature: it enhances defensive tools while posing existential threats to public key encryption algorithms, for example, RSA (Rivest-Shamir-Adleman). A mature quantum computer could decrypt data that classical systems would take billions of years to crack, enabling “store-now-decrypt-later” attacks.
Consequently, the guide positions post-quantum cryptography (PQC) as a cornerstone of quantum cybersecurity, urging immediate adoption to counter such risks. It also explores quantum communications, such as quantum key distribution (QKD), which offers unbreakable encryption by detecting eavesdropping through quantum physics principles.
Strategic Principles for Cybersecurity
ITI’s guide outlines six strategic principles, with Principle 3 focusing on cybersecurity and privacy implications. This principle advocates for adaptive, risk-based policies combining PQC and quantum communications.
For instance, the U.S. National Institute of Standards and Technology (NIST) leads PQC standardization, developing quantum-resistant algorithms to enhance threat detection in large datasets. However, PQC is not provably secure, requiring organizations to manage residual risks strategically.
Quantum communications, including quantum random number generators (QRNG) and QKD, offer provably secure solutions, though scalability remains a challenge. The guide recommends policies to incentivize R&D to mature these technologies, ensuring flexibility for countries to tailor approaches based on threat tolerance.
[ Gaining first mover advantage in quantum technologies – particularly quantum computing – can offer countries and private sector companies significant strategic benefits. However, these strategic advances come with risks, such as high research and development (R&D) costs, supply chain challenges, technology unpredictability and the challenge of building a skilled workforce ... ]

Collaboration is an imperative for transitioning to new standards, with public-private partnerships driving the integration of quantum-decryption threats into cyber-threat modeling and incident response. Privacy concerns, such as quantum sensing’s potential for invasive monitoring, underscore the need for robust policies.
Before imposing new regulations, The guide advises evaluating existing cybersecurity frameworks thus ensuring a balanced approach fostering innovation.
Practical Applications and Global Cooperation
The guide showcases practical applications, such as securing multi-orbit satellite communications with crypto-agile, quantum-resilient communication channels. Other examples studied demonstrate need for measurable successes in finance and infrastructure, reinforcing the urgency of PQC adoption.
Additionally, global cooperation is vital, with two international forums, the Organisation for Economic Co-operation and Development (OECD) and World Economic Forum (WEF) recommended for coordinating standards. Export controls and investment screening must balance security with innovation, ensuring transparent processes among allies. This global lens highlights cybersecurity as a collaboration among nations to address supply chain vulnerabilities and workforce gaps.
Ultimately, ITI’s guide serves as a blueprint for policymakers to capture quantum’s $600 billion to $750 billion potential while safeguarding data. By advocating for hybrid strategies, proactive migrations, and global engagement, ITI positions quantum cybersecurity as the cornerstone of resilient innovation. Governments and companies must act swiftly to stay ahead in the quantum race, particularly against adversarial nations and competitors, ensuring a secure and prosperous quantum future.
