As quantum computing becomes increasingly prevalent, businesses must prepare for a drastic leap in sophisticated cyber threats. According to experts, including Michael Cavallin, cybersecurity manager for British Columbia Investment Management Corp., and Melanie Anderson, information assurance director general for the Canadian Centre for Cyber Security, whatever is created today will be decryptable in the future. This poses significant financial and confidentiality risks for businesses of all sizes, as well as threats to national security data.
The potential moment when quantum computers could break all conventional encryption safeguards, known as “Q-Day,” could arrive by the 2030s. To protect themselves, businesses can adopt post-quantum cryptography, or quantum-safe cryptography, which creates cryptographic algorithms invulnerable to quantum computers. Key players in this field include the National Institute of Standards and Technology, which has finalized three standards for new encryption algorithms, and companies like Microsoft, Volkswagen AG, Daimler Motors Corp., and Airbus SE, which are already utilizing quantum computing to improve performance and efficiency.
Preparing for Quantum Cyber Threats: The Countdown to Q-Day
As quantum computing becomes increasingly pervasive, businesses must prepare for a drastic leap in sophisticated cyber threats. Experts warn that whatever is created today will be decryptable in the future, and that starts now. This poses significant financial and confidentiality risks for businesses of all sizes and threats to nuclear codes and national security data.
One of the biggest concerns is cryptography, as those with access to quantum technology could easily decrypt confidential code from conventional computers. Michael Cavallin, cybersecurity manager for British Columbia Investment Management Corp., urged organizations to consider potential data exposure consequences and prepare. He also warned about supercharging AI with quantum computing, noting that attackers can already successfully impersonate others.
The Decryption Issue: Q-Day and Beyond
Melanie Andreson, information assurance director general for the Canadian Centre for Cyber Security, highlighted the decryption issue, warning that “Q-Day”—the potential moment when quantum computers could break all conventional encryption safeguards—could arrive by the 2030s. She emphasized that a sufficiently powerful quantum computer will break the encryption that underpins literally everything we do on the Internet today.
Anderson explained that traditional computers use two bits – ones and zeros – to make calculations, whereas quantum computers rely on qubits, capable of superposition – simultaneously being a one and zero. This allows them to calculate all possible values in a single operation and enable previously impossible computations.
Protecting Against Quantum Computers: Post-Quantum Cryptography
So, how do businesses protect themselves from quantum computers? Anderson advises that planning is essential while it’s not time to panic. Post-quantum cryptography, or quantum-safe cryptography, creates cryptographic algorithms invulnerable to quantum computers that run on classical systems.
Anderson emphasized the importance of strong, secure cryptographic standards as the foundation of good cyber defense. She noted that certified products are expected to be released in 2025-26 and advised people to start the transition then. In 2016, the National Institute of Standards and Technology issued a call for new encryption algorithms to withstand quantum computer attacks, resulting in the development of three standards: ML-KEM for key establishment, ML-DSA for digital signatures, and SLH-DSA for special-purpose digital signatures.
The Quantum Computing Industry: A Growing Force
The quantum computing industry is projected to be a US$131-billion industry by 2040, with the first commercially viable fault-tolerant quantum computer expected by 2029. Currently, there are 27 quantum initiatives worldwide, and countries behind these initiatives have invested US$42 billion. The private sector has also invested US$8.5 billion to drive commercialization.
Applications range from materials to pharmaceuticals, with early quantum computers ideal for solving combinatorial problems where a small number of data points need to be entered before working on a massive space. One application could be in medicine, discovering new drugs and better understanding existing diseases.
Quantum computing could especially benefit artificial intelligence, machine learning, and language models due to quick calculation capacity and lower energy usage. According to Louise Turner, CEO of the Quantum Algorithms Institute, “By the same token, AI and machine learning models will then help improve how we use quantum computers.”
Business Recommendations: Planning for the Future
Asked for business recommendations, Turner said it depends on circumstances. For small businesses holding substantial financial information or larger companies and accounting firms, planning should start now. Smaller organizations using Microsoft 365 as their primary software suite might receive quantum protection through software updates.
However, organizations with vital data requiring 10-year protection should consider impacts now, Anderson emphasized. As the countdown to Q-Day begins, it’s essential for businesses to stay ahead of the curve and prepare for the impending threats posed by quantum computing.
