DEVICE-INDEPENDENT QUANTUM SECURED COMMUNICATION
Abstract
Quantum mechanics can be exploited to enable communication protocols with security guarantees going beyond what is possible with classical physics. In this proposed work, we will identify the fundamental resources for so-called “device-independent” quantum information protocols, which are robust against untrusted devices and measurements. Our approach will combine a deep understanding of the convex structure of quantum-achievable probability distributions together with a novel method for establishing performance bounds on quantum-information-theoretic tasks. We will develop new tools in convex geometry, based on recent results in the field, to identify the underlying resources common to all device-independent protocols. This will most directly lead to better protocols for device-independent quantum cryptography and secure communication, and may also yield improvements in different information-theoretic tasks such as secure computation and high-quality random number generation. The insights of this work will also help identify new tasks that can be made more secure with a device-independent implementation.
