Proposal for witnessing non-classical light with the human eye

TL;DR

This paper proposes a method to demonstrate non-classical light detection using the human eye as a detector, leveraging sub-Poissonian states, displacement operations, and statistical analysis.

Contribution

It introduces a novel approach to witness non-classical photonic states directly with the human eye, combining quantum optics techniques with human perception models.

Findings

A few tens of hours are sufficient to certify non-classical light with 10% p-value.

The proposal accounts for realistic imperfections in photon creation and detection.

The human eye can serve as a practical detector for quantum optical experiments.

Abstract

We give a complete proposal showing how to detect the non-classical nature of photonic states with naked eyes as detectors. The enabling technology is a sub-Poissonian photonic state that is obtained from single photons, displacement operations in phase space and basic non-photon-number-resolving detectors. We present a detailed statistical analysis of our proposal including imperfect photon creation and detection and a realistic model of the human eye. We conclude that a few tens of hours are sufficient to certify non-classical light with the human eye with a p-value of 10%.
