Peter Shor’s algorithm could break the internet – but he's not worried
Few people have invented an algorithm with the potential to spark a worldwide crisis, so why is quantum computing pioneer Peter Shor so unconcerned? Karmela Padavic-Callaghan spoke to him to find out

The intersection of Peter Shor’s foundational quantum algorithm and the fragility of modern encryption systems isn’t just a technical curiosity—it’s a ticking clock for global cybersecurity. His work threatens to unravel decades of cryptographic infrastructure overnight, exposing vulnerabilities that nations and corporations have only recently begun to grapple with. The fact that Shor himself remains unconcerned speaks volumes about the misalignment between theoretical breakthroughs and practical preparedness, revealing a critical gap in how we prioritize and mitigate existential technological risks.
Background Context
Shor’s algorithm, developed in 1994, demonstrated that a sufficiently powerful quantum computer could factor large integers exponentially faster than classical machines—effectively cracking widely used encryption standards like RSA. Yet despite its theoretical menace, the algorithm’s real-world impact has been muted by the glacial pace of quantum hardware development and the cryptographic community’s slow but growing adaptation to post-quantum encryption methods. Meanwhile, governments and corporations continue to rely on systems built for a pre-quantum era, gambling with billions in digital infrastructure.
What Happens Next
Expect an acceleration in the migration to quantum-resistant encryption, but not before a period of heightened exposure to state-sponsored hacking and cyber espionage. The lag between Shor’s warning and widespread implementation of safeguards could create a window of vulnerability, particularly as quantum advancements outpace defensive measures. Watch for regulatory mandates in critical sectors like finance and defense, as well as a scramble among tech giants to patent post-quantum cryptographic solutions before the market consolidates.
Bigger Picture
This moment underscores a broader pattern in tech history: the lag between disruptive innovation and societal adaptation. Just as the internet’s architecture once ignored security in favor of speed, today’s encryption ecosystem risks repeating those mistakes. The difference now is the stakes—quantum computing isn’t just another upgrade, but a potential paradigm shift that could redefine power structures in cybersecurity, geopolitics, and digital sovereignty for decades to come.
