Surpassing the currently achievable distance of quantum key distribution based on sending-or-not-sending approach
Georgi Bebrov
Protocols based on the sending-or-not-sending (SNS) principle have been intensively studied in recent years and have been shown to enable the longest transmission distances in quan…

On the Optimality of a Quantum Key Distribution
Georgi Bebrov
Quantum key distribution (QKD) systems require optimal performance of both quantum and classical channels - utilizing as few as possible qubits and bits for establishing as many as…

Quantum Key Distribution Based on Systematic Polar Coding
Georgi Bebrov
Here we concerned with quantum key distribution - a way to establish common cryptographic key between several parties. The work proposes a combination between quantum key distribut…
