Researchers from the University of the Witwatersrand in Johannesburg, South Africa (Wits University), working with Huzhou University in China, have discovered a way to protect quantum information from environmental interference. This is a breakthrough that could lead to more reliable quantum technologies.
In a study published on March 26 in Nature Communications, the team showed that certain quantum states can retain their essential information even when exposed to environmental “noise” that would normally disrupt them.
“What we’ve found is that topology is a powerful resource for information encoding in the presence of noise,” says Professor Andrew Forbes from the Wits School of Physics.
