Device-independent quantum key distribution (DIQKD) provides the strongest form of secure key exchange, using only the input-output statistics of the devices to achieve information-theoretic security. Although the security principles of DIQKD are now well-understood, it remains a technical challenge to derive reliable security bounds for generic DIQKD protocols beyond the standard ones. In this Letter, we present a numerical framework based on semi-definite programming that gives reliable lower… CONTINUE READING
