Simple Mod Can Keep Quantum States 10,000 Times Longer

Technological advancements have allowed physicists to manipulate and study quantum particles, their states, and their interactions. However, they still need to figure out how to keep quantum systems from decaying long enough to practically run computations and transfer information—and a simple solution might just solve the problem
