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

Abstract

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.

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.

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

Amir Feizpour, Xingxgin Xing, Aephraim M. Steinberg

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.

Enhanced Probing of Fermion Interaction by Weak Value Amplification

Alex Hayat, Amir Feizpour, Aephraim M. Steinberg

We propose a scheme for weak-value amplification of probing a single-fermion interaction, and demonstrate it theoretically on quantum dot electron spins by mapping the state including energy and spin into a photon.

Lossless transformation of coherent light into amplitude-squeezed light

Klaus M. Gheri, Daniel F. Walls

We show that the use of weakly probed three-level atoms in the \ensuremath{\Lambda} configuration as a nonlinear medium inside an optical cavity enables the almost lossless transformation of an incoming strong coherent light beam into an outgoing amplitude-squeezed light beam.

Weak measurement amplification in optomechanics via a squeezed coherent state pointer

Gang Li, Li-Bo Chen, Xiu-Min Lin +1 more

Abstract We present a scheme for achieving amplification of the displacement of a mirror in an optomechanical cavity using single-photon postselection where the mirror is initially prepared in a squeezed coherent state. The amplification depends on the enhanced fluctuations of the squeezed coherent state and is caused by the noncommutativity of quantum mechanics relying on the squeezed coherent state, which cannot be explained by the standard weak measurement theory [1, 25].
