Paper: Quantum Supremacy Using a Programmable Superconducting Processor Authors: Frank Arute et al. Published: Nature, 2019 Summary This landmark paper from Google AI Quantum demonstrates quantum computational supremacy using their 53-qubit Sycamore processor. The team showed that their quantum computer could perform a specific task (random circuit sampling) in 200 seconds that would take the world’s most powerful supercomputer approximately 10,000 years. Key Contributions First demonstration of quantum supremacy: This was the first experimental evidence that quantum computers can outperform classical computers for certain tasks. ...

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. ...
