Progress on Problem about Quantum Hamming Bound for Impure Quantum Codes [PDF]
arXiv, 2009 A famous open problem in the theory of quantum error-correcting codes is whether or not the parameters of an impure quantum code can violate the quantum Hamming bound for pure quantum codes. We partially solve this problem. We demonstrate that there exists a threshold such that an arbitrary quantum code must obey the quantum Hamming bound whenever . We

Temperature‐Induced Effects on Wet‐Spun Artificial Spider Silk Fibers
Advanced Functional Materials, EarlyView.Silk‐based materials are valued for their strength and flexibility, but temperature effects on their mechanical properties are understudied. This study examines the properties of artificial silk fibers from −80 to +120 °C. Results show maintained strength at high temperatures and increased strength at low temperatures. Abstract Silk‐based materials are

Advanced Functional Materials, EarlyView.This study presents a method to create atomically flat dielectric patterns of SiO2 and AlOx for MoSe2 monolayers, forming lateral heterojunctions with minimal strain. The dielectric pattern modulates excitonic properties, contact potential, and carrier dynamics, demonstrating a tunable approach for enhancing the optoelectronic properties of 2D ...

Medium‐Entropy Engineering of Magnetism in Layered Antiferromagnet CuxNi2(1‐x)CrxP2S6
Advanced Functional Materials, EarlyView.This study explores the aliovalent substitution strategy with Cu and Cr replacing Ni in Ni₂P₂S₆ compounds to engineer magnetism. By creating CuxNi2(1‐x)CrxP2S6 medium‐entropy alloys, the research reveals the evolution of distinct magnetic phases, including the creation of weak ferromagnetism in intermediate compositions.

Comparison of memory thresholds for planar qudit geometries
New Journal of Physics, 2017 We introduce and analyze a new type of decoding algorithm called general color clustering, based on renormalization group methods, to be used in qudit color codes.

A note on one-way quantum deficit and quantum discord [PDF]
Quantum Inf. Process. 15 (2016) 279, 2016 One-way quantum deficit and quantum discord are two important measures of quantum correlations. We revisit the relationship between them in two-qubit systems. We investigate the conditions that both one-way quantum deficit and quantum discord have the same optimal measurement ensembles, and demonstrate that one-way quantum deficit can be derived from ...
