TL;DR
This paper introduces a concatenation-based method for constructing quantum error-correcting codes specifically designed to correct amplitude damping errors, resulting in codes with improved parameters over previous methods.
Contribution
The paper presents a novel concatenation approach using asymmetric CSS codes as inner codes and symmetric error-correcting codes as outer codes, leading to better quantum codes for amplitude damping errors.
Findings
New quantum codes with improved parameters
Codes outperform previous amplitude damping codes
Effective construction method for amplitude damping error correction
Abstract
We discuss a method to construct quantum codes correcting amplitude damping errors via code concatenation. The inner codes are chosen as asymmetric Calderbank-Shor-Steane (CSS) codes. By concatenating with outer codes correcting symmetric errors, many new codes with good parameters are found, which are better than the amplitude damping codes obtained by any previously known construction.
