Quantum hashing via single-photon states with orbital angular momentum [PDF]
Physical Review A, 2021 Quantum hashing is a promising generalization of the cryptographic hashing concept on the quantum domain. In this paper, we construct a quantum hash via a sequence of single-photon states and perform a proof-of-principle experiment using orbital angular ...

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

One-Time Universal Hashing Quantum Digital Signatures without Perfect Keys [PDF]
Physical Review Applied, 2023 Quantum digital signatures (QDS), generating correlated bit strings among three remote parties for signatures through quantum law, can guarantee non-repudiation, authenticity, and integrity of messages. Recently, one-time universal hashing QDS framework,

On quantum collision resistant function
Учёные 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
IACR 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 ...

Analysis of the amplitude form of the quantum hash function
Учёные записки Казанского университета: Серия Физико-математические науки, 2023 In this article, the properties of quantum hash functions are further explored. Previous findings show that so-called small-bias sets (special subsets of the set of elements of a cyclic group) generate a “phase” quantum hash function. Here, it was proved
