Chip-based quantum key distribution [PDF]
Nature Communications, 2017 Quantum key distribution has not been widely adopted in part due to technical hurdles preventing it being fully integrated in classical communication networks.

Decoherence-assisted quantum key distribution [PDF]
Scientific ReportsWe put forward and demonstrate a controllable decoherence-assisted quantum key distribution scheme. The protocol is based on the possibility of introducing controllable decoherence to polarization qubits using the spatial degree of freedom of light.

Mode-pairing quantum key distribution
Nature Communications, 2022 Measurement-device-independent QKD schemes suffer from a trade-off between ease of implementation (avoiding the need for global phase locking) and high rates (quadratic improvement in rate).

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.

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 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 ...

Fully Passive Quantum Key Distribution
Physical Review Letters, 2023 Passive implementations of quantum key distribution (QKD) sources are highly desirable as they eliminate side-channels that active modulators might introduce. Up till now, passive decoy-state and passive encoding BB84 schemes have both been proposed.

Layered quantum key distribution [PDF]
Physical Review A, 2018 We introduce a family of QKD protocols for distributing shared random keys within a network of $n$ users. The advantage of these protocols is that any possible key structure needed within the network, including broadcast keys shared among subsets of users, can be implemented by using a particular multi-partite high-dimensional quantum state.

Quantum dense key distribution [PDF]
Physical Review A, 2004 This paper proposes a new protocol for quantum dense key distribution. This protocol embeds the benefits of a quantum dense coding and a quantum key distribution and is able to generate shared secret keys four times more efficiently than BB84 one. We hereinafter prove the security of this scheme against individual eavesdropping attacks, and we present ...
