Summary form only given. Quantum information theory suggests the possibility of accomplishing tasks that are beyond the capability of classical computer science, such as information-secure cryptographic key distribution. The lack of security proofs for standard (secret- and public-) key distribution schemes, and the insecurity of the most widely used classical schemes (such as RSA and PGP) against "quantum attacks" emphasises the need for information-secure key distribution. We provide a…

### Fully device independent quantum key distribution

- Computer ScienceCommun. ACM
- 2019

This work rigorously proves the device-independent security of an entanglement-based protocol building on Ekert's original proposal for quantum key distribution and builds on techniques from the classical theory of pseudo-randomness to achieve a new quantitative understanding of the non-local nature of quantum correlations.

This paper surveys the quantum key distribution protocols which exist in literature and explores the attacks to which they are vulnerable and highlights the main implementation bottlenecks related with each implementation and the solutions proposed thereof.

### Implementation vulnerabilities in general quantum cryptography

- Computer Science, PhysicsNew Journal of Physics
- 2018

This work surveys quantum digital signatures, quantum secret sharing, source-independent quantum random number generation, quantum secure direct communication, and blind quantum computing and proposes how the eavesdropper could in principle exploit the loopholes to violate assumptions in these protocols, breaking their security properties.

It is found that unitary bases are central to both encryption of quantum information, as well as the generation of states used in generalized quantum key distribution (which are called mutually unbiased bases).

### Practical quantum key distribution with geometrically uniform states

Basic techniques to prove the unconditional security of quantum crypto graphy are described and a practical variation on the protocol in which the channel is noisy and photos may be lost during the transmission is considered.

### Quantum cryptography with coherent states

- Computer Science, PhysicsTechnical Digest. CLEO/Pacific Rim'95. The Pacific Rim Conference on Lasers and Electro-Optics
- 1995

This work discusses quantum cryptographic protocols based on the transmission of weak coherent states and presents a system, based on a symbiosis of two existing systems, for which the information available to the eavesdropper is significantly reduced and is therefore safer than the two previous ones.

### Quantum memory in quantum cryptography

This work defines strong attacks of this type, and shows security against them, suggesting that quantum cryptography is secure, and suggests a new type of quantum key distribution scheme where quantum memories are used instead of quantum channels.

### Quantum Key Distribution and String Oblivious Transfer in Noisy Channels

- Computer Science, MathematicsCRYPTO

A lemma is proved that extends a security proof given by Yao for a (one bit) QOT protocol to this String-QOT protocol, which implies the unconditional security of the QKD protocol despite the previous proof that unconditionally secure bit commitment schemes are impossible.
