Calgary Tests Quantum Shields for City Safety

Calgary is testing quantum technology to keep city systems safe from hackers. At the Wave Tech Centre, experts showed how quantum-based security can protect data moving between sensors and city servers. The demo was part of a global challenge that brings together cities and companies to find new ways to protect critical infrastructure. The initiative aims to see if these tools can stop attacks before they cause damage.

The city relies on sensor networks to watch water levels in the Bow River and control traffic lights. These systems run essential services, so a break-in could cause real problems. Jason Cameron, who runs the tech centre, says the bigger worry isn't just stolen data, but someone taking over the actual machines that keep the city running. He wants the public to understand that infrastructure safety matters more than data privacy.

Recent attacks in France shut down supermarket freezers, wasting millions of dollars of food. In Ukraine, hackers knocked out power grids. Those stories show what’s at stake if city controls are tampered with. Cameron asks what would happen if dam gates opened or a power plant shut down unexpectedly. He says the consequences could affect thousands of residents in seconds.

Quantum tools could help stay ahead of those threats, he says. The Quantum City Global Challenge drew entries from eight countries. Toshiba was named the global winner, and KETS Quantum Security took the startup prize. Calgary will use its own municipal infrastructure to test the tech and see if it’s ready for wider use. The goal is to decide later whether quantum security earns a spot in future city budgets. Testing will show if the technology is mature enough for real-world protection of city services. The city hopes to share results with other municipalities soon.
