Microscopic mechanism of 'quantum collapse' in real-world environments uncovered for the first time
Why it matters: This discovery provides a pathway to connect ideal quantum theory to practical and reliable quantum engineering.
- Professor JaeDong Lee's team at DGIST developed a novel computational approach using the Lindblad master equation to account for electron-electron and electron-environment interactions.
- The research identified that interference between superradiance and broadband emission leads to mutual cancellation, causing ultrafast electronic decoherence in solids.
- The study is published in the journal Advanced Science, with Gimin Bae et al. listed as authors, and is expected to bridge the gap between ideal quantum theory and practical quantum technologies.
Scientists have finally uncovered the microscopic mechanism behind 'quantum collapse' in real-world environments, a phenomenon known as ultrafast electronic decoherence that disrupts quantum states within femtoseconds. This breakthrough, led by Professor JaeDong Lee's team at DGIST, reveals that environmental interactions, specifically the interplay between superradiance and broadband emission, are the decisive factor in this long-standing mystery.
