Dynamic Range Reduction via Branch-and-Bound
Thore Gerlach, Nico Piatkowski·Sep 17, 2024
A key strategy to enhance specialized hardware accelerators, such as GPUs and FPGA, is to reduce the numerical precision in arithmetic operations, which increases processing speed and lowers latency-both crucial for real-time AI applications. In this...
A Symbol-Pair Decoder for CSS Codes
V. Jha, P. Udaya, Abhay Kumar Singh·Sep 17, 2024
The relation between stabilizer codes and binary codes provided by Gottesman and Calderbank et al. is a celebrated result, as it allows the lifting of classical codes to quantum codes. An equivalent way to state this result is that the work allows us...
