Introduction

Quantum computing is transitioning from theoretical to practical application, promising significant advancements across various sectors. However, this technological leap also poses substantial risks to current cybersecurity infrastructures—especially for small businesses.

Understanding the Quantum Threat

Traditional encryption methods, such as RSA and ECC, rely on mathematical problems that are currently infeasible for classical computers to solve. Quantum computers, leveraging principles of quantum mechanics, can process information in fundamentally different ways. Algorithms like Shor’s algorithm can efficiently factor large numbers, rendering current encryption methods vulnerable once sufficiently powerful quantum computers become available.

This vulnerability means that data encrypted today could be decrypted in the future—a concept known as “harvest now, decrypt later.” Adversaries might collect encrypted data now, anticipating the ability to decrypt it once quantum computing matures. Source: Wikipedia

Why Small Businesses Should Be Concerned

Small businesses often assume they’re too insignificant to be targeted. However, they are increasingly becoming prime targets due to typically having less robust security measures compared to larger enterprises. The advent of quantum computing exacerbates this risk, as the tools to break encryption become more powerful and accessible. For context, our recent analysis of cybersecurity challenges in 2025 highlights how small businesses are facing growing threats from sophisticated cyber attacks.

Moreover, regulatory bodies are beginning to recognize the impending quantum threat. For instance, the UK’s National Cyber Security Centre advises organizations to start planning a migration to post-quantum cryptography by 2028 to avoid last-minute chaos. Source: Financial Times

Real-World Examples and Statistics

• In 2023, 61% of cyberattacks were aimed at small and medium-sized businesses (SMBs), with 48% experiencing a cybersecurity incident between 2022 and 2023. The average data breach cost for companies with fewer than 500 employees was $3.31 million in 2023. Source: NAVEX

• A survey by KPMG in Canada found that about 60% of organizations in Canada and 78% in the US expect quantum computers to become mainstream by 2030. However, 62% in Canada and 81% in the US admit they need to better evaluate their current capabilities. Source: KPMG

Steps to Prepare for the Quantum Era

1. Stay Informed About Post-Quantum Cryptography (PQC): PQC involves developing cryptographic algorithms that are secure against quantum attacks. The National Institute of Standards and Technology (NIST) has finalized standards for several PQC algorithms, including CRYSTALS-Kyber for encryption and CRYSTALS-Dilithium for digital signatures.

2. Assess Your Current Cryptographic Assets: Conduct an inventory of your current encryption methods and identify which systems and data are most vulnerable to quantum attacks. This should align with your broader IT infrastructure review.

3. Develop a Migration Plan: Plan your transition to PQC. Update software, hardware, and protocols to support the new standards. Partner with a managed IT service provider to guide the process.

4. Educate Your Team: Train your IT staff and employees on quantum risks. Incorporate this into broader cybersecurity awareness programs.

5. Consult with Cybersecurity Experts: Bring in professionals who understand quantum computing and PQC to help build a resilient defense strategy.

Regulatory Developments

Recognizing the urgency of the quantum threat, the U.S. government has taken proactive steps. In January 2025, President Biden issued Executive Order 14144, mandating federal agencies to prepare for a transition to quantum-resistant cryptographic algorithms. This directive emphasizes the need for secure software development practices and the adoption of emerging technologies to bolster the nation’s cybersecurity. Source: The American Presidency Project

Industry Perspectives

Industry leaders are also sounding the alarm. Jay Gambetta, Vice President of IBM Quantum, stated, “If you’re not paying attention and you’re not dedicating people to quantum computing, I think it’s probably already too late.” This underscores the imperative for businesses to prioritize quantum readiness.
