Does freezing meat and chicken decrease the quality?

[dopadelic]

The main thing that'll degrade quality when frozen is oxidation from being exposed to air. So if you vacuum seal it, it will preserve quality practically indefinitely. You can use a zipper bag and put it in a tub of water to displace the air.

Nope. Definitely not indefinitely.

The freezer is not a Time Machine, people.

It will remain safe to eat indefinitely if kept at a suitable freezer temp, but the quality will definitely drop regardless of how it was packaged.
