Quantum Privacy and Schur Product Channels
, 2017 We investigate the quantum privacy properties of an important class of quantum chan-nels, by making use of a connection with Schur product matrix operations and associated correlationmatrix structures.

Post-Quantum Key Agreement Protocol based on Non-Square Integer Matrices
, 2023 We present in this paper an algorithm for exchanging session keys, coupled with a hashing encryption module. We show schemes designed for their potential invulnerability to classical and quantum attacks.

Approximate Quasiorthogonality of Operator Algebras and Relative Quantum Privacy [PDF]
, 2019 We show that the approximate quasiorthogonality of two operator algebras is equivalent to the algebras being approximately private relative to their conditional expectation quantum channels.

A multi-channel quantum image representation model with qubit sequences for quantum-inspired image and image retrieval [PDF]
Quantum image processing (QIP) has become one of the most significant fields in quantum computing (QC); it merges quantum mechanics with image processing to improve classical image-processing speed, which involves various operations to advance quantum ...

Simple and tight device-independent security proofs [PDF]
, 2019 Device-independent security is the gold standard for quantum cryptography: not only is security based entirely on the laws of quantum mechanics, but it holds irrespective of any a priori assumptions on the quantum devices used in a protocol, making it ...
