Bounds for Pure Disjoint -Quantum Locally Recoverable Codes
Evagoras Stylianou, Holger Boche
We study pure disjoint -quantum locally recoverable codes (qLRCs) without assuming a stabilizer structure. We formulate local Knill--Laflamme conditions for recovery from up…
CSS Quantum LRCs with Intersecting Recovery Sets: Constructions and Bounds
Evagoras Stylianou, Vinayak Ramkumar, Holger Boche +1
In this work, we study quantum locally recoverable codes (qLRCs) with locality , recovery sets per qudit, and intersection parameter . We first show that, assum…
Implicit and Explicit Formulas of the Joint RDF for a Tuple of Multivariate Gaussian Sources with Individual Square-Error Distortions
Evagoras Stylianou, Charalambos D. Charalambous, Themistoklis Charalambous
This paper analyzes the joint Rate Distortion Function (RDF) of correlated multivariate Gaussian sources with individual square-error distortions. Leveraging Hotelling's canonical…
Entanglement-assisted Quantum Error Correcting Code Saturating The Classical Singleton Bound
Soham Ghosh, Evagoras Stylianou, Holger Boche
We introduce a construction for entanglement-assisted quantum error-correcting codes (EAQECCs) that saturates the classical Singleton bound with less shared entanglement than any k…
Indirect Rate Distortion Functions with Side Information: Structural Properties and Multivariate Gaussian Sources
Evagoras Stylianou, Michail Gkagkos, Charalambos D. Charalambous
In this paper, we analyze the indirect source coding problem with side information at both the encoder and decoder, as well as only at the decoder. We first derive structural prope…
Minimal Trellises for non-Degenerate and Degenerate Decoding of Quantum Stabilizer Codes
Evagoras Stylianou, Vladimir Sidorenko, Christian Deppe +1
This paper presents a comprehensive guide to designing minimal trellises for both non-degenerate and degenerate decoding of quantum stabilizer codes. For non-degenerate decoding, v…
