Will Quantum Computing Help Recover the Forever Lost Bitcoins?
What Are the “Forever Lost” Bitcoins? There's bitcoins that are considered lost forever.
I got Two questions:
  1. Will Quantum computing help recover the forever lost bitcoins?
  2. Who will own the lost bitcoins after being recovered?
How Are These Bitcoins Protected?
The vast majority of Bitcoin wallets, use standard ECC—specifically ECDSA with wallet address types such as: P2PKH, P2SH, P2WPKH and P2TR
Anyone who controls the key controls the coins.
Will Lost Bitcoins Be Recovered, or Simply Stolen?
If quantum computing becomes practically scalable, it will only make Bitcoin even stronger.

That's going to be the next debate.
Steal or burn.
For now I'm on the steal side.

Probably yes. Most likely the cost of “stealing” those coins will be close to their value though. As it currently happens with: https://privatekeyfinder.io/bitcoin-puzzle/

I consider that any coins up for grabs that don’t move to quantum secure addresses to be a prize to whoever achieves quantum supremacy first.
Also only coins in old P2PK addresses, and P2TR addresses are immediately vulnerable. Also any coins in other addresses that have been re-used (ie: already spent from).
Any addresses that are a “pay to hash” type are safe from immediate threats up until an attacker has a quantum computer fast enough to derive the private key in the time between when a payment is broadcast until it’s included in a block, since the public key isn’t revealed until it’s spent from. So coins lost forever in these addresses will likely remain lost forever.

All active users will move to quantum resistant addresses everything else will be as a gold under ground, people will start mining these lost Bitcoin with quantum Asics. We will never have more than 2.1 quadrillion sats

That's a nice way to put it. Just a new kind of mining.

My counter question. Will "Quantum Computing" ever have any practical use?

We are SO far away from that. Not even sure whether this will ever happen. As far as I am aware, the largest number that was successfully factored with Shor's algorithm is 21. 😂️
