Ultra-secure communication networks powered by quantum technology are being developed by a team of researchers at the University of Toronto to protect information security from future cyber threats – advancing the next generation of cybersecurity resilience.
Their work uses “entangled photons” to create fundamentally secure communication links. Since measuring or copying these particles instantly reveals any attempt to listen in on the signal, the technology is ideal for securing defence communications and critical infrastructure signals for everything from banking data to national defence communications.
A key focus of the research addresses a key issue: transmitting quantum signals over long distances without losing them. Solving this issue is essential to building scalable, real-world quantum communication networks that can operate reliably across regions.
