The history of work on quantum computers dates back to 1990s. So I would say, Satoshi would have known that quantum computers will become a reality in future which will have an ability to break any cryptographic hash. But that might not be the immediate concern for him because if quantum computers actually become a reality, then more than Bitcoin many other technology will be in problem. So, there will definitely be a way out.
He was more centered towards creating a decentralized currency than being concerned about something that will not become a reality in near future.

It wouldn't be right to think of Bitcoin or Blockchain for the last 10 years. For a decentralized structure, it is necessary to look at 1990. You need to look at even older dates. Bitcoin is the result of the CyperPunk stream. This is my opinion. Satoshi presented us with 30 years of experience. I think Quantum Computers are also guessing.
Unlikely for anything to break crypto any time soon. Besides, addresses are hashes of public keys which are not known until a spend transaction is visible. By the time that is done, it will be too late for any computer, quantum or not, to break it and get the private key in order to attempt to double spend anything.
Satoshi trusted cryptography. That means didn't plan anything in case P=NP or in case quantum computers will exist/work as advertised. Also he probably didn't plan bitcoin to be so successful.
If anything breaks cryptography, it doesn't matter what Satoshi believed. Bitcoin will cease to exist.
If anything breaks cryptography, it doesn't matter what Satoshi believed. Bitcoin will cease to exist.
Even though there are lots of work going towards the existence of quantum computer still it has not come to reality yet. And there are lots of ongoing work regarding the development of crypto too which will have no value if the quantum computers come into existence. People/companies are also spending money even on post-quantum computing to be secure against an attack by a quantum computer.
At the time of creation of BTC, the case of the existence of quantum computer was not considered as it was not considered in many of the cases. Now the developers are certainly finding defence system for any post-quantum attack.

'According to the “Quantum Computing Technologies & Global Market – 2018-2024” report, the global Quantum Computing market* will reach $10.7 billion by 2024, out of which $8.45 billion stem from product sales and services and $2.25 billion from government-funded RDT&E programs.'

'How can BTC be Protected from Quantum Computers? Simply put, p2pkh addresses that were not previously used for spending Bitcoin should be perfectly safe. Their public keys were not revealed to the public, meaning that not even quantum computers can use them to derive a private key. All that people need to do is transfer their BTC to a new p2pkh address, and their funds should be perfectly safe.'

But Satoshi had mined more than the above mentioned coins. He had several computers to mine and his own coins are unknown. Some say these coins decrease the total number of coins as they can't be used. But in 2009 we had an agreement that the supply limit is 21 million BTC and that limit won't be changed. They will become active and all coins will be used.

Satoshi knew that one day quantum computers will exist and will be able to move the early mined coins (P2PK) and created an unofficial prize competition to accelerate the development.

If they are speculating that Quantum computer could make the blockchain obsolete then i can speculate that the bitcoin core will come up with a solutionThat's not an issue. Bitcoin developers have already post quantum solutions.
But there are lots of 'shalecoins', https://bitcointalksearch.org/topic/bitcoin-as-shalecoin-5134441 coins with no owner. With quantum computers, these coins will become active and change the Bitcoin ecosystem.
Satoshi had already thought of the quantum computers, and the possible decoding of the privatekeys if it became available, ..
His coins would be quantum secured, if he sent them to P2PKH addresses. But he did not and isn't doing.2. Satoshi created the greatest prize competition and the privatekeys are somehow within the blockchain. https://bitcointalksearch.org/topic/maybe-satoshi-created-the-greatest-prize-competition-5150688
and privatekeys are somehow within the blockchain = quantum computer?
We will get the answer with quantum computers. As soon as possible.
Researchers from the Russian Quantum Center suggested that quantum computing could eventually obsolete blockchain altogether.
If they are speculating that Quantum computer could make the blockchain obsolete then i can speculate that the bitcoin core will come up with a solution that could secure even the quantum attack and then they will spend another billion to do further research to break those system and it will be a never ending battle and once they burn enough billions they will eventually stop these bullshit research

He knew.
Either way, we are still likely decades away from this threatening bitcoin.
we are currently no where near the physical qubits to be overly concerned.
Thank you.
"In order to have any effect on bitcoin or most other financial systems it would take at least about 1500 qubits and the system must allow for the entanglement of all of them," "By comparison, Google's measly 53 qubits are still no match for this kind of cryptography."

For faster quantum computing, Microsoft builds a better qubit - Microsoft's new approach to quantum computing is "very close," an executive says.
"We've really spent the recent few years developing that technology," Krysta Svore, general manager of Microsoft's quantum computing software work, said Thursday after a talk at the IEEE International Conference on Rebooting Computing. "We believe we're very close to having that." Specifically, she thinks one logical qubit will require 10 to 100 physical qubits with Microsoft's topological qubits. That compares to something like 1,000 to 20,000 physical qubits for other approaches.

Satoshi Nakamoto is a mathematician. I am a physicist. I had a mathematics professor that could be compared with Satoshi Nakamoto. When bitcoin was invented in 2009, the quantum adventure was at its beginnings.
I made my PhD thesis on quantum wells (in 2000), in 2009 what was in my PhD thesis was learned in the QM in the 2nd year of faculty. When bitcoin was invented no one could say that Quantum Computers will be invented in 10 years.
Thus, Satoshi Nakamoto did not think that quantum computers will exist when he invented the bitcoin.

There are not many quantum computers in the world, and if someone wants to crack cryptography they will have very big problems. So I think no one dares to do it
Satoshi has mined the most coins.
In 2010 they were talking about lost coins and Satoshi said
1. He thought the coins are lost forever and we have a lot of 'shalecoins' https://bitcointalksearch.org/topic/bitcoin-as-shalecoin-5134441 and they will become active one day
or
2. Satoshi created the greatest prize competition and the privatekeys are somehow within the blockchain. https://bitcointalksearch.org/topic/maybe-satoshi-created-the-greatest-prize-competition-5150688

Satoshi is a rogue AI from the future, running on a time-traveling quantum computer. Bizarre, and the stuff movies are made from. That's what I choose to believe: he's the quantum computer himself.
