Signal-to-Noise Ratio Enhancement in Weak Measurement, and its Application to Observing Single-Photon-Level Nonlinearities

Abstract

We show theoretically that weak-value amplification can enhance the signal-to-noise ratio in the presence of noise with long correlation times, in particular for measurements of single-photon-level nonlinearities.

Amplifying Single-Photon Nonlinearity Using Weak Measurements

Amir Feizpour, Xingxing Xing, Aephraim M. Steinberg

We show that weak measurement can be used to "amplify" optical nonlinearities at the single-photon level, such that the effect of one properly postselected photon on a classical beam may be as large as that of many unpostselected photons. We find that "weak-value amplification" offers a marked improvement in the signal-to-noise ratio in the presence of technical noise with long correlation times. Unlike previous weak-measurement experiments, our proposed scheme has no classical equivalent.

Squeezed Light in Weak Value Amplification for Single-Photon-Level Nonlinearity

F. Matsuoka, Akihisa Tomita, Akihiro Okamoto

We propose the use of a squeezed coherent light probe in weak value amplification of single photon nonlinearity. It improves the success probability more than tenfold without the degradation of the error probability.

Increasing the Signal-to-Noise Ratio in Weak-Value Measurements

By recycling non-post selected photons through a Sagnac interferometer in our optical weak measurement of a mirror tilt, we double the detected intensity, resulting in a signal-to-noise ratio improvement of 1.57 over un-recycled experiments.
