Downhole sensing using parametric amplification with squeezed or entangled light for internal mode input |
| abstract |
A downhole sensing system includes an optical sensor that provides a light signal with at least one attribute related to a downhole parameter. The system also includes a parametric amplification module that amplifies the light signal using squeezed or entangled light for internal mode input. The system also includes a processing unit that determines a value for the downhole parameter based on the amplified light signal. |
