Elements of Quantum Information Theory,m, including the notions of qubits, entanglement and general quantum operations (Sects. .–.). We then introduce the entropies characterizing information-processing tasks which commonly occur in quantum cryptography, in particular the Shannon and von Neumann entropy (Sect. .), the min- and max-entrop

Introducing Quantum Key Distribution, this Chapter we first present some of the security principles of QKD in Sect. .. We then describe the BB84 protocol as an example of QKD protocol and compute its key rate (Sect. .). Section . is bit more technical, here we define and prove the security of a generic QKD protocol in the finite-key sc

Quantum Conference Key Agreement,and present the multipartite generalization of the BB84 protocol, including insight on its security proof and asymptotic key rate. In Sect. . we describe the functioning of a general CKA protocol and define its security, which is proven in Sect. . of the Appendix. We conclude the Chapter by discussi

Quantum Key Distribution with Imperfect Devices,e then focus on the solutions to such problems, which are given by a combination of theoretical advances and clever experimental design. In particular, in Sects. . and . we discuss how security can be proven when the BB84 protocol is implemented with weak coherent pulses instead of single-photon sou

Beyond Point-to-Point Quantum Key Distribution,ct. .). Subsequently, we present in detail the (arguably) simplest solution found by researchers to overcome such limitations, which is twin-field (TF) QKD. TF-QKD overcomes the point-to-point private capacity by exploiting single-photon interference in an intermediate untrusted station (Sects. . an

Book 2021ocols promise everlasting security by exploiting distinctive quantum properties of nature. The most extensively implemented protocol is quantum key distribution (QKD), which enables secure communication between two users. The aim of this book is to introduce the reader to state-of-the-art QKD and il
