Cybersecurity today often feels like a never-ending contest between attackers and defenders. New threats emerge, and companies respond with stronger locks and barriers. But what if security could be built so firmly into the foundation of digital systems that certain attacks were not just difficult but impossible? This vision points to a structural shift in how we think about protecting data.
Currently, two main strategies dominate. The first is Quantum Key Distribution (QKD), which uses the strange laws of quantum physics. In simple terms, if someone tries to intercept a quantum signal, the very act of looking at it changes the signal itself, alerting the sender and receiver. It’s a powerful safeguard, but its strength comes passively from physics.
The second strategy is Post-Quantum Cryptography (PQC). Instead of physics, PQC relies on complex mathematical puzzles that even powerful quantum computers are believed to be unable to solve efficiently. Governments and institutions, such as NIST, have begun standardizing these algorithms. Yet, this protection is based on assumptions. We trust that the math is hard, but there is no absolute proof it will remain that way.
Both QKD and PQC are crucial, but they are reactive, methods developed to counter threats rather than reimagine security itself.
This is where a new theoretical approach, called the Quaternary Interpretation of Quantum Dynamics (QIQD), comes in. QIQD suggests that the limits we currently see in quantum mechanics such as the rule that signa
