Hybrid Continuous-discrete Variable Quantum Key Distribution
Guangtongxin yanjiu, 2023 As one of the main applications of quantum cryptography, Quantum Key Distribution (QKD) is a promising secure key transmission method. Compared with traditional communication methods, QKD protocols based on the basic principles of quantum mechanics have ...

Quantum state redistribution based on a generalized decoupling
, 2008 We develop a simple protocol for a one-shot version of quantum state redistribution, which is the most general two-terminal source coding problem. The protocol is simplified from a combination of protocols for the fully quantum reverse Shannon and fully ...

Puncturing Quantum Stabilizer Codes [PDF]
IEEE Journal on Selected Areas in Information TheoryClassical coding theory contains several techniques to obtain new codes from other codes, including puncturing and shortening. Both of these techniques have been generalized to quantum codes.

Generalizing Quantum Tanner Codes
2024 IEEE International Symposium on Information Theory Workshops (ISIT-W)In this work, we present a generalization of the recently proposed quantum Tanner codes by Leverrier and Zémor, which contains a construction of asymptotically good quantum LDPC codes. Quantum Tanner codes have so far been constructed equivalently from groups, Cayley graphs, or square complexes constructed from groups.

Towers of generalized divisible quantum codes [PDF]
Physical Review A, 2018 A divisible binary classical code is one in which every code word has weight divisible by a fixed integer. If the divisor is $2^ $ for a positive integer $ $, then one can construct a Calderbank-Shor-Steane (CSS) code, where $X$-stabilizer space is the divisible classical code, that admits a transversal gate in the $ $-th level of Clifford hierarchy.

General entanglement-assisted quantum error-correcting codes [PDF]
Physical Review A, 2007 Entanglement-assisted quantum error-correcting codes (EAQECCs) make use of pre-existing entanglement between the sender and receiver to boost the rate of transmission. It is possible to construct an EAQECC from any classical linear code, unlike standard QECCs which can only be constructed from dual-containing codes.

Quantum generalized Reed-Solomon codes: Unified framework for quantum MDS codes
, 2008 We construct a new family of quantum MDS codes from classical generalized Reed-Solomon codes and derive the necessary and sufficient condition under which these quantum codes exist. We also give code bounds and show how to construct them analytically.

Advanced Engineering Materials, EarlyView.A wood‐based magnetic and conductive material called Magwood (MW), capable of blocking almost 99.99% of electromagnetic waves (in the X‐band frequency range), is synthesized using a simple, solvent‐free process. MW is lightweight, resists water, and is flame‐retardant, making it a promising alternative for shielding electronics. The rapid proliferation

Second-Order Asymptotics of Visible Mixed Quantum Source Coding via Universal Codes [PDF]
IEEE Transactions on Information Theory, 2014 The simplest example of a quantum information source with memory is a mixed source, which emits signals entirely from one of two memoryless quantum sources with given a priori probabilities.
