![]() ![]() This method can find direct application to nondestructive measurements in quantum systems, such as for the generation of spin-squeezed states in atom interferometers and atomic clocks. The demonstrated method provides a flexible situation by using an optical ring cavity and two independent beams. Additionally, we apply this noise-reduced phase shift measurement scheme in a simulated spin-squeezing experiment where we have achieved a factor of 40 improvement in phase sensitivity with a phase resolution of 0.7 mrad, which may remove one important barrier against attaining highly spin-squeezed states. Its been a while, but Ive been looking for something like this. Ill try my rock band drums when i get home. cavity configuration can provide hemispherical unambiguous direction of. Theres a great youtuber, Sodamlazy, whos done a whole bunch of charts and has videos of them on his channel 1. Various noise sources are analyzed and their contributions to the noise floor are evaluated. Single sensor phase shift DOA measurement presented a resolution better than 3. The differential error signal shows a 30 dB reduction in cavity noise down to the noise floor in a frequency range up to half the cavity linewidth ( δ ν / 2 ≃ 30 kHz). Two laser beams with a frequency difference of one cavity free spectral range are simultaneously resonant with the cavity, demonstrating noise correlations in the error signals due to the common-mode cavity length fluctuations. We demonstrate a method of light phase shift measurement using a high-finesse optical ring cavity which exhibits reduced phase noise due to cavity length fluctuations.
