Quantum 'dark modes' no longer block phonon control, opening new paths for scalable devices

Phys · · 449 words · By RIKEN

Three RIKEN researchers have developed a method to counteract 'dark modes' in non-Hermitian quantum systems, which previously suppressed desired quantum effects. By engineering these dark modes to temporarily behave as 'bright modes,' the team achieved precise topological control over phonons. The research suggests this advance could facilitate the development of scalable quantum devices.

“Dark modes are so-called because they are 'invisible' to the environment or to the driving field that couples to a system's other modes, which are bright modes.”
SINGLE SOURCE
The concept of 'dark modes' being invisible to the environment or driving field is mentioned in the context of the quantum physics articles, but the web search results for this specific claim are dominated by results for the TV show 'Dark' (which is irrelevant). The quantum context is present in the search results, but not corroborated by multiple independent sources specifically defining the term.

“The team was able to engineer dark modes by introducing artificial quantum information to the system.”
INSUFFICIENT EVIDENCE
Although the overall context is about engineering dark modes, none of the provided web search results contain specific evidence stating that the team engineered dark modes *by introducing artificial quantum information* into the system. The evidence is silent on the mechanism of 'artificial quantum information'.
help
“The trio anticipates that the demonstration will help to develop new devices and find new effects.”
INSUFFICIENT EVIDENCE
No evidence was found in the web search results to support the claim that the trio anticipates developing new devices or finding new effects; the evidence only reports the demonstration itself.
