Symmetric Autocompensating Quantum Key Distribution [PDF]

open access: yesSPIE Proceedings, 2003
We present quantum key distribution schemes which are autocompensating (require no alignment) and symmetric (Alice and Bob receive photons from a central source) for both polarization and time-bin qubits.

Free-space quantum key distribution [PDF]

open access: yesPhysical Review A, 1998
A working free-space quantum key distribution (QKD) system has been developed and tested over a 205-m indoor optical path at Los Alamos National Laboratory under fluorescent lighting conditions.

Quantum Key Distribution [PDF]

open access: yesACM 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]

open access: yesQuantum, 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.

Experimental Twin-Field Quantum Key Distribution over 1000 km Fiber Distance. [PDF]

open access: yesPhysical 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.

Continuous-variable quantum key distribution system: Past, present, and future [PDF]

open access: yesApplied Physics Reviews, 2023
Quantum key distribution provides secure keys with information-theoretic security ensured by the principle of quantum mechanics. The continuous-variable version of quantum key distribution using coherent states offers the advantages of its compatibility ...

Quantum Key Distribution Networks: Challenges and Future Research Issues in Security

open access: yesApplied 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]

open access: yesQuantum, 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,
