A Few Photons Became a Mechanical State With 76 Percent Efficiency
A millikelvin optomechanical crystal mapped weak optical pulses into a localized GHz mode and back.
Summary
A millikelvin optomechanical crystal mapped weak optical pulses into a localized GHz mode and back.
The experiment reports 0.76 conversion efficiency, a 7.3-microsecond storage lifetime and bandwidth above 4.5 MHz near the single-quantum regime. Correlation measurements support coherent retrieval, though the added thermal occupation remains nine quanta.
Why it matters
A millikelvin optomechanical crystal mapped weak optical pulses into a localized GHz mode and back.
Limits and context
No additional limitation was separately recorded.
Key claims
