Quantum error correction is a crucial aspect of quantum computing, ensuring the stability and reliability of quantum information. Here are some key research papers on quantum error correction:

  • "Fault-Tolerant Quantum Computation with Constant Error Rate" by Shor and DiVincenzo This seminal paper introduces fault-tolerant quantum computation and the threshold theorem, which is fundamental for the practical realization of quantum computers.

  • "Quantum Error Correction and Fault-Tolerance" by Steane This paper discusses the Steane code, a linear error-correcting code that is particularly effective for correcting errors in quantum systems.

  • "Quantum Error Correction with Linear Optics" by Knill, Laflamme, and Milburn This research explores the use of linear optics for quantum error correction, which is a promising approach for scalable quantum computing.
