Experimental demonstration of a graph state quantum error-correction code

Understand

Scalable quantum computing and communication requires the protection of quantum information from the detrimental effects of decoherence and noise.

• Previous work tackling this problem has relied on the original circuit model for quantum computing.
• However, recently a family of entangled resources known as graph states has emerged as a versatile alternative for protecting quantum information.
• Depending on the graph's structure, errors can be detected and corrected in an efficient way using measurement-based techniques.
