Quantum Strongly Secure Ramp Secret Sharing [PDF]
, 2014 Quantum secret sharing is a scheme for encoding a quantum state (the secret) into multiple shares and distributing them among several participants. If a sufficient number of shares are put together, then the secret can be fully reconstructed.

Private quantum codes: introduction and connection with higher rank numerical ranges
, 2013 We give a brief introduction to private quantum codes, a basic notion in quantum cryptography and key distribution. Private code states are characterized by indistinguishability of their output states under the action of a quantum channel, and we show ...

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 ...
