Trellis Decoding for Qudit Stabilizer Codes and Its Application to Qubit Topological Codes

2024 · IEEE Transactions on Quantum Engineering

Trellis decoders are a general decoding technique first applied to qubit-based quantum error correction codes by Ollivier and Tillich in 2006. Here, we improve the scalability and practicality of their theory, show that it has …

CAFQA: A Classical Simulation Bootstrap for Variational Quantum Algorithms

2022

Classical computing plays a critical role in the advancement of quantum frontiers in the NISQ era. In this spirit, this work uses classical simulation to bootstrap Variational Quantum Algorithms (VQAs). VQAs rely upon the iterative …

QUITS: A modular Qldpc code circUIT Simulator

2025 · arXiv (Cornell University)

To achieve quantum fault tolerance with lower overhead, quantum low-density parity-check (QLDPC) codes have emerged as a promising alternative to topological codes such as the surface code, offering higher code rates. To support their study, …
