Quantum key distribution without sending a quantum signal [PDF]
New Journal of Physics, 2015 Quantum Key Distribution is a quantum communication technique in which random numbers are encoded on quantum systems, usually photons, and sent from one party, Alice, to another, Bob. Using the data sent via the quantum signals, supplemented by classical

Quantum Key Distribution Using Quantum Faraday Rotators [PDF]
Journal of Physics: Condensed Matter, 2007 We propose a new quantum key distribution (QKD) protocol based on the fully quantum mechanical states of the Faraday rotators. The protocol is unconditionally secure against collective attacks for multi-photon source up to two photons on a noisy ...

Fully Passive Quantum Key Distribution [PDF]
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.

DECOY STATE QUANTUM KEY DISTRIBUTION
International Islamic University Malaysia Engineering Journal, 2010 Experimental weak + vacuum protocol has been demonstrated using commercial QKD system based on a standard bi-directional ‘Plug & Play’ set-up. By making simple modifications to a commercial quantum key distribution system, decoy state QKD allows us to ...

Quantum Key Distribution Using a Quantum Emitter in Hexagonal Boron Nitride [PDF]
Advanced Quantum Technologies, 2023 Quantum key distribution (QKD) is considered the most immediate application to be widely implemented among a variety of potential quantum technologies. QKD enables sharing secret keys between distant users by using photons as information carriers.

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.
