Quantum Distance Bounding: Advancing Secure Proximity

Have you ever considered how we can securely confirm someone's physical proximity in our digital world? In this talk, we'll explore Quantum Distance Bounding—an approach that uses the principles of quantum physics to determine an upper limit on the distance between two parties. This method enhances security by using qubits instead of traditional signals like radio waves or ultrasound, offering robust protection against various types of attacks. We'll discuss the fundamental concepts, potential applications, and how this technology could influence the future of secure communications.
