Popis:	We introduce a family of high-rate amplitude-damping (AD) Shor Codes, designed to effectively correct AD errors while maintaining immunity to collective coherent (CC) errors. The proposed $[[(w+1)(w+K), K]]$ AD codes can approximately correct up to $w$ AD errors, with flexible parameters $(w, K)$, and we provide a rigorous proof that these codes satisfy the approximate quantum error correction conditions. These AD Shor codes employ structured stabilizer measurement schemes, allowing efficient detection of AD errors using local operations and ancillary qubits. By concatenating these codes with the dual-rail code, we construct a class of CC-AD Shor codes that inherit the advantageous properties of the AD Shor codes. Comment: 4 pages, 2 figures, 2 tables
