Major Quantum Computing Strategy Suffers Serious Setbacks

10/16/2021

This article discusses the setbacks faced by a major quantum computing strategy known as "fault-tolerant quantum computing." The strategy involves using error-correcting codes to protect quantum information from errors caused by noise and imperfections in quantum hardware. However, recent research has shown that encoding and decoding these error-correcting codes introduces its own set of challenges and can lead to additional errors. The article highlights the difficulties in achieving fault-tolerant quantum computing, including the need for a large number of qubits and more stable quantum systems. Despite these setbacks, researchers remain optimistic and continue to explore alternative approaches to quantum computing.
