Hiding Single Photons With Spread Spectrum Technology

TL;DR

This paper demonstrates a proof-of-principle experiment applying spread spectrum technology to single photons, enabling their hiding and recovery amidst noise, with potential applications in quantum communication.

Contribution

It introduces the novel use of spread spectrum techniques at the single photon level for secure quantum information transmission.

Findings

Single photons can be effectively hidden using spread spectrum methods.

The technique allows recovery of the photons despite interfering noise.

Proof-of-principle experiment validates the approach.

Abstract

We describe a proof-of-principal experiment demonstrating the use of spread spectrum technology at the single photon level. We show how single photons with a prescribed temporal shape, in the presence of interfering noise, may be hidden and recovered.
