Receiver-Device-Independent Quantum Key Distribution [PDF]
Quantum, 2022 We present protocols for quantum key distribution in a prepare-and-measure setup with an asymmetric level of trust. While the device of the sender (Alice) is partially characterized, the receiver's (Bob's) device is treated as a black-box.

Quantum Key Distribution [PDF]
ACM Computing Surveys, 2020 The convergence of quantum cryptography with applications used in everyday life is a topic drawing attention from the industrial and academic worlds. The development of quantum electronics has led to the practical achievement of quantum devices that are already available on the market and waiting for their first application on a broader scale.

Experimental Twin-Field Quantum Key Distribution over 1000 km Fiber Distance. [PDF]
Physical Review Letters, 2023 Quantum key distribution (QKD) aims to generate secure private keys shared by two remote parties. With its security being protected by principles of quantum mechanics, some technology challenges remain towards practical application of QKD.

Quantum Key Distribution Networks: Challenges and Future Research Issues in Security
Applied Sciences, 2021 A quantum key distribution (QKD) network is proposed to allow QKD protocols to be the infrastructure of the Internet for distributing unconditional security keys instead of existing public-key cryptography based on computationally complex mathematical ...

Explicit asymptotic secret key rate of continuous-variable quantum key distribution with an arbitrary modulation [PDF]
Quantum, 2021 We establish an analytical lower bound on the asymptotic secret key rate of continuous-variable quantum key distribution with an arbitrary modulation of coherent states. Previously, such bounds were only available for protocols with a Gaussian modulation,

Quantum cryptography: Public key distribution and coin tossing [PDF]
Theoretical Computer Science, 2014 When elementary quantum systems, such as polarized photons, are used to transmit digital information, the uncertainty principle gives rise to novel cryptographic phenomena unachievable with traditional transmission media, e.g. a communications channel on

Security of device-independent quantum key distribution protocols: a review [PDF]
Quantum, 2022 Device-independent quantum key distribution (DI-QKD) is often seen as the ultimate key exchange protocol in terms of security, as it can be performed securely with uncharacterised black-box devices.

Implementation Security in Quantum Key Distribution [PDF]
Advanced Quantum Technologies, 2023 The problem of implementation security in quantum key distribution (QKD) refers to the difficulty of meeting the requirements of mathematical security proofs in real‐life QKD systems. Here, a succint review is provided on this topic, focusing on discrete‐
