Quantum turbo codes (QTCs) are known to operate close to the achievable Hashing bound.However, the sequential nature of the conventional quantum turbo decoding algorithm Cheese Knife imposes a high decoding latency, which increases linearly with the frame length.This posses a potential threat to quantum systems having short coherence times.

In this context, we conceive a fully-parallel quantum turbo decoder (FPQTD), which eliminates the inherent time dependences of the conventional decoder by executing all the associated processes concurrently.Due to its parallel nature, the proposed FPQTD reduces the decoding times by several orders of magnitude, while maintaining the same performance.We have also demonstrated the significance of employing an odd-even interleaver design in conjunction with the proposed FPQTD.

More specifically, it is shown that an odd-even interleaver reduces the computational complexity by 50%, Body Sponge without compromising the achievable performance.
