Surface Codes: Towards Practical Large-Scale Quantum Computation
Paper: Surface Codes: Towards Practical Large-Scale Quantum Computation Authors: Austin G. Fowler, Matteo Mariantoni, John M. Martinis, Andrew N. Cleland Published: Physical Review A, 2012 Summary This paper provides a comprehensive introduction to surface code quantum error correction, arguably the most promising approach for building fault-tolerant quantum computers. The authors detail how surface codes can achieve high error thresholds (~1%) with only nearest-neighbor interactions, making them particularly suitable for 2D qubit arrays. ...
