In a feat of physics judo, researchers have harnessed the same forces that usually destroy long-range quantum links between particles to generate those connections.

This counterintuitive approach may produce “extremely long-lived” quantum links, researchers report in a paper appearing online at the physics website arXiv.org. Long-lasting, room temperature quantum effects are ideal for designing systems that can reliably exchange quantum information.
