Recent advances in quantum computing could mean a faster internet, but it’s also raising concerns among some privacy advocates who warn that quantum breakthroughs could put users’ data at risk.
An international research team recently took a leap toward building a high-performing, scalable "quantum internet." The team achieved sustained, long-distance teleportation through 27 miles of optical fiber, according to a new paper in the peer-reviewed journal PRX Quantum. A functional quantum internet would dramatically change the fields of secure communication, data storage, and computing.
One side effect for users with the advent of quantum computing is that current security schemes could become easy to break. Quantum computing could allow malicious hackers to compromise internet protocols such as HTTPS and TLS required for secure browsing, online banking, and online shopping, Ulf Mattsson, Chief Security Strategist at the cybersecurity firm Protegrity, said in an email interview.
