Depolarizing Channel Mismatch and Estimation Protocols for Quantum Turbo Codes [PDF]

open access: yesEntropy, 2019
Quantum turbo codes (QTC) have shown excellent error correction capabilities in the setting of quantum communication, achieving a performance less than 1 dB away from their corresponding hashing bounds.

Quantum hashing and Fourier transform

open access: yesJournal of Physics: Conference Series, 2020
In the paper based on the notion of small-biased sets we define the quantum transformation that describes the quantum hash function over the cyclic group. We discuss its similarity to the well-known Quantum Fourier Transform and show possible applications to constructing space-efficient algorithms in various computational scenarios, including two-party

Chosen-Prefix Collisions on AES-like Hashing [PDF]

open access: yesIACR Transactions on Symmetric Cryptology
Chosen-prefix collision (CPC) attack was first presented by Stevens, Lenstra and de Weger on MD5 at Eurocrypt 2007. A CPC attack finds a collision for any two chosen prefixes, which is a stronger variant of collision attack. CPCs are naturally harder to

Quantum search in a dictionary based on fingerprinting-hashing

open access: yesCoRR
In this work, we present a quantum query algorithm for searching a word of length $m$ in an unsorted dictionary of size $n$. The algorithm uses $O(\sqrt{n})$ queries (Grover operators), like previously known algorithms. What is new is that the algorithm is based on the quantum fingerprinting-hashing technique, which (a) provides a first level of ...

EXIT-Chart Aided Design of Irregular Multiple-Rate Quantum Turbo Block Codes

open access: yesIEEE Access, 2023
We propose a novel quantum turbo short-block code, which subsumes multiple-rate quantum short-block codes (MR-QSBCs) as the outer codes and a quantum unity-rate code (QURC) as the inner code. The proposed design is denoted as MR-QSBC-QURC.

On quantum collision resistant function

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки, 2021
In the classical hashing theory, collision is a coincidence of the values of a function with different arguments. This paper formulates a quantum analogue of the collision property.

Quantum Period Finding is Compression Robust

open access: yesIACR Transactions on Symmetric Cryptology, 2022
We study quantum period finding algorithms such as Simon and Shor (and its variant Ekerå-Håstad). For a periodic function f these algorithms produce – via some quantum embedding of f – a quantum superposition ∑x |x〉 |f(x)〉, which requires a certain ...

User privacy prevention model using supervised federated learning‐based block chain approach for internet of Medical Things

open access: yesCAAI Transactions on Intelligence Technology, EarlyView., 2023
Abstract This research focuses on addressing the privacy issues in healthcare advancement monitoring with the rapid establishment of the decentralised communication system in the Internet of Medical Things (IoMT). An integrated blockchain homomorphic encryption standard with an in‐build supervised learning‐based smart contract is designed to improvise ...
