If I was the tournament organizer, all games would be held inside windowless, sound proof rooms doubling as Faraday cages with thick concrete walls, electronic jammers outside to prevent any radio communications, and no one but cleared staff members inside. The players would also be subjected to multiple rounds of metal detectors.

Can metal detector detect a gram of Silicon(except transistor I think there are non metallic replacement for everything)? Also, many players bring their own beverage in their container. Seems pretty steep to ban everything for a small minority of cheater.

Can a computer small enough to contain a chess engine be fitted into one gram?

The players beverages would also have to be taken out of their original container and transferred into a tournament-provided container.

IBM has 1mm * 1mm chip comparable in performance to 1990 Intel, likely much lower in weight than 1g along with photovoltaic cell for power[0]. I don't think this is enough for beating Magnus, but it could at least find tactics.

For me it is unbelievable that it is not done that way already.

It is like hearing about ambassadors who dont implement strict rules to defend the embassy against spies.
