The security of measurement device-independent quantum key distribution (MDI QKD) relies on a thorough characterization of one's optical source output, especially any noise in the state preparation process. Here, we provide an extension of the loss-tolerant protocol [Phys. Rev. A 90, 052314 (2014)], a leading proof technique for analyzing the security of QKD, to MDI QKD protocols that employ mixed signal states. We first reframe the core of the proof technique, noting its generalization to… Expand

Computing secure key rates for quantum key distribution with untrusted devices
TLDR
This Letter presents a numerical framework based on semi-definite programming that gives reliable lower bounds on the asymptotic secret key rate of any QKD protocol using untrusted devices. Expand

TLDR
This work proposes an approach which allows us to study general physical systems for which the above mentioned independence condition does not necessarily hold, and introduces new uncertainty measures, called smooth min- and max-entropy, which are generalizations of information-theoretical notions.

TLDR
Containing a wealth of figures and exercises, this well-known textbook is ideal for courses on the subject, and will interest beginning graduate students and researchers in physics, computer science, mathematics, and electrical engineering. Expand
Quantum information and computation
TLDR
In information processing, as in physics, the classical world view provides an incomplete approximation to an underlying quantum reality that can be harnessed to break codes, create unbreakable codes, and speed up otherwise intractable computations. Expand
