Daylight entanglement-based quantum key distribution with a quantum dot source [PDF]
Quantum Science and Technology, 2022 Entanglement-based quantum key distribution can enable secure communication in trusted node-free networks and over long distances. Although implementations exist both in fiber and in free space, the latter approach is often considered challenging due to ...

Quantum and Semi–Quantum key Distribution in Networks
International Journal of Theoretical Physics, 2023 In this paper, we utilize the potential offered by multidimensional separable states (MSS) for secure and simultaneous distributions of keys in a layered network. We present protocols for both quantum and semi-quantum key distribution and discuss their robustness against various eavesdropping strategies. We provide a procedure to identify the requisite

Practical issues of twin-field quantum key distribution
New Journal of Physics, 2019 Twin-field quantum key distribution(TF-QKD) protocol and its variants, such as phase-matching QKD, sending-or-not-sending QKD and no phase post-selection TF-QKD(NPP-TFQKD), are very promising for long-distance applications.

Higher-rate relativistic quantum key distribution
Scientific Reports, 2021 One of the major problems in the field of quantum key distribution (QKD) is the low key rates at which the systems operate. The reasons for this are the processes used to ensure the key distribution itself: sifting, parameter estimation, key ...

Noiseless Linear Amplifiers in Entanglement-Based Continuous-Variable Quantum Key Distribution
Entropy, 2015 We propose a method to improve the performance of two entanglement-based continuous-variable quantum key distribution protocols using noiseless linear amplifiers. The two entanglement-based schemes consist of an entanglement distribution protocol with an

Loophole-free plug-and-play quantum key distribution
New Journal of Physics, 2021 Robust, simple, and flexible quantum key distribution (QKD) is vital for realizing practical applications of this technique. Contrary to typical phase-coded QKD schemes, the plug-and-play QKD design requires only one arm-length-insensitive interferometer

Secure quantum key distribution with realistic devices
, 2020 Some years ago quantum hacking became popular: devices implementing the unbreakable quantum cryptography were shown to have imperfections which could be exploited by attackers.

IEEE Access, 2017 In this paper, we propose an efficient and deterministic quantum key distribution protocol for establishing a secret key between two untrusted users. In this protocol, a secret key is distributed to a sender and a receiver who share entangled states with

Receiver-device-independent quantum key distribution protocols
New Journal of Physics, 2022 We discuss quantum key distribution protocols and their security analysis, considering a receiver-device-independent (RDI) model. The sender’s (Alice’s) device is partially characterized, in the sense that we assume bounds on the overlaps of the prepared

Attacks against a Simplified Experimentally Feasible Semiquantum Key Distribution Protocol
Entropy, 2018 A semiquantum key distribution (SQKD) protocol makes it possible for a quantum party and a classical party to generate a secret shared key. However, many existing SQKD protocols are not experimentally feasible in a secure way using current technology. An
