Quantum Hyperdense Coding for Distributed Communications
Sandor Imre
Superdense coding proved that entanglement-assisted quantum communications can improve the data transmission rates compared to classical systems. It allows sending 2 classical bits…
Properties of the Quantum Channel
Laszlo Gyongyosi, Sandor Imre
Quantum information processing exploits the quantum nature of information. It offers fundamentally new solutions in the field of computer science and extends the possibilities to a…
Algorithmic Superactivation of Asymptotic Quantum Capacity of Zero-Capacity Quantum Channels
Laszlo Gyongyosi, Sandor Imre
The superactivation of zero-capacity quantum channels makes it possible to use two zero-capacity quantum channels with a positive joint capacity for their output. Currently, we hav…
Quasi-Superactivation of Classical Capacity of Zero-Capacity Quantum Channels
Laszlo Gyongyosi, Sandor Imre
One of the most surprising recent results in quantum Shannon theory is the superactivation of the quantum capacity of a quantum channel. This phenomenon has its roots in the extrem…
Information Geometric Security Analysis of Differential Phase Shift Quantum Key Distribution Protocol
Laszlo Gyongyosi, Sandor Imre
This paper analyzes the information-theoretical security of the Differential Phase Shift (DPS) Quantum Key Distribution (QKD) protocol, using efficient computational information ge…
An Improvement in Quantum Fourier Transform
Laszlo Gyongyosi, Sandor Imre
Singular Value Decomposition (SVD) is one of the most useful techniques for analyzing data in linear algebra. SVD decomposes a rectangular real or complex matrix into two orthogona…
