TV and Video Game Streaming with a Quantum Receiver: A Study on a Rydberg atom-based receivers bandwidth and reception clarity

TL;DR

This study demonstrates that Rydberg atom-based receivers can effectively receive live color TV and video game signals, with performance influenced by beam size, achieving high fidelity at optimal dimensions.

Contribution

The paper introduces a novel application of Rydberg atom receivers for analog video signals and analyzes how beam size impacts bandwidth and reception quality.

Findings

Small beam diameters (<100 μm) enable faster response times.

Optimal beam width of 85 μm yields high-fidelity color reception.

Rydberg atom receivers can handle over 3 MHz bandwidth for 480i signals.

Abstract

We demonstrate the ability to receive live color analog television and video game signals with the use of the Rydberg atom receiver. The typical signal expected for traditional 480i NSTC format video signals requires a bandwidth of over 3 MHz. We determine the beam sizes, powers, and detection method required for the Rydberg atoms to receive this type of signal. The beam size affects the average time the atoms remain in the interaction volume, which is inversely proportional to the bandwidth of the receiver. We find that small beam diameters (less than 100 {\mu}m) lead to much faster responses and allow for color reception. We demonstrate the effect of beam size on bandwidth by receiving a live 480i video stream with the Rydberg atom receiver. The best fidelity was achieved with a beam width of 85 {\mu}m full-width at half-max.
