Multiparty mediated quantum secret sharing protocol [PDF]
Quantum Information Processing, 2022 This study proposes a multiparty mediated quantum secret sharing (MQSS) protocol that allows n restricted quantum users to share a secret via the assistance of a dishonest third-party (TP) with full quantum capabilities. Under the premise that a restricted quantum user can only perform the Hadamard transformation and the Z-basis measurement, the ...

Local Search and the Evolution of World Models
Topics in Cognitive Science, EarlyView., 2023 Abstract An open question regarding how people develop their models of the world is how new candidates are generated for consideration out of infinitely many possibilities. We discuss the role that evolutionary mechanisms play in this process. Specifically, we argue that when it comes to developing a global world model, innovation is necessarily ...

Controlled quantum secret sharing [PDF]
Physica Scripta, 2006 We present a new protocol in which a secret multiqubit quantum state $\ket $ is shared by $n$ players and $m$ controllers, where $\ket $ is the encoding state of a quantum secret sharing scheme. The players may be considered as field agents responsible for carrying out a task, using the secret information encrypted in $\ket $, while the controllers ...

Dynamic hierarchical quantum information sharing protocol
网络与信息安全学报, 2016 Quantum secret sharing (QSS) is one important branch of quantum cryptography.Based on the studies of multi-shared quantum bits,a new dynamic quantum bit sharing protocol was proposed.The participation of the shared members is hierarchical in this ...

Breaking the rate-distance limitation of measurement-device-independent quantum secret sharing
Physical Review Research, 2023 Currently most progress on quantum secret sharing suffers from rate-distance bound, and thus the key rates are limited. In addition to the limited key rate, the technical difficulty and the corresponding cost together prevent large-scale deployment ...

Dynamic Multiparty Quantum Secret Sharing With a Trusted Party Based on Generalized GHZ State
IEEE Access, 2021 This paper proposes a dynamic multiparty to multiparty quantum secret sharing scheme, where two distant groups of participants can share the common secrets.

Angewandte Chemie, EarlyView.A novel carbon dots material (BUL‐CDs) with an initial afterglow brightness (406 cd m−2) far exceeding that of other afterglow luminescent materials was developed. Furthermore, the BUL‐CDs exhibited time‐dependent afterglow colors, excitation‐dependent afterglow colors, and thermochromic afterglow in response to triplet variables.

Computational Quantum Secret Sharing
, 2023 Quantum secret sharing (QSS) allows a dealer to distribute a secret quantum state among a set of parties so that certain subsets can reconstruct the secret, while unauthorized subsets obtain no information. While QSS was introduced over twenty years ago, previous works focused only on existence of perfectly secure schemes, and the share size of the ...
