For faster quantum computing, Microsoft builds a better qubit
Google just announced quantum supremacy, a milestone in which the radically different nature of a quantum computer lets it vastly outpace a traditional machine. But Microsoft expects progress of its own by redesigning the core element of quantum computing, the qubit.
Microsoft has been working on a qubit technology called a topological qubit that it expects will deliver benefits from quantum computing technology that today are mostly just a promise.
"We've really spent the recent few years developing that technology," Krysta Svore, general manager of Microsoft's quantum computing software work, said. "We believe we're very close to having that."
The key advantage of Microsoft's topological qubit is that fewer physical qubits are needed to make one logical qubit, Svore said.
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.
Topic: Did Satoshi think that quantum computers will exist? - page 5. (Read 1929 times)
From the topic subject, it seems that you are already assuming that quantum computers will impact the bitcoin and bitcoin community big. Well, in my point, we need first to gather information with regards to quantum computers and its possible potential to affect cryptocurrency. In this case, making an assumption about Satoshi and bitcoin community having a risk with quantum computers.
Why do I need to tell you this?
Simple, because our words are powerful and it can affect the mindset of mostly newbies in the cryptocurrency space to believe that quantum computers do really might harm the blockchain.

Yes, for sure Satoshi is one of the genius people, who devoted their time and life for doing something amazing just like Bitcoin or crypocurrency, and for sure he knows that technology will continue to develop more over the years, so it doesn't matter whether he predicted it or not, what matters is that he created something different.
Maybe, he already knew that quantum will exist because blockchain was develop and study for long years and quantum as well. satoshi might know or already heard that quantum developers are already having ideas for doing this and also for sure that satoshi is not afraid of that because he also have the idea that this have a disadvantage. blockchain will remain that everyone needed. the idea of satoshi is a far different from this new quantum technology.
He probably had them in mind, at least as a possibility. He's likely the only one who can answer with any certainty, but I think that he must have had them in mind, since he's clearly well-educated and thoughtful.
Satoshi is much aware of quantum computer and its upcoming supremacy but satoshi bitcoin alogarthim is much advance than all these features of quantum computing

The blockchain community should immediately begin working on three issues to prevent being overtaken by quantum computers, a cryptography expert says. Xinxin Fan, head of cryptography at privacy- and IoT-focused blockchain platform IoTeX, published an article in The International Business Times on Nov. 7, calling on the blockchain community to be constantly updated about the progress made on quantum computers.

In particular, all coins suspected to be Satoshi's are in P2PK outputs. If those moved ever, even to a different sig algo, it would cause enormous chaos.
assuming satoshi can still move their/his coins, this is a likely reason why it's not happening. Although we shouldn't discount the most conservative thing that all 2009 era mined BTC key holders could do; start by moving their BTC with the highest block number, and do it very very slowly. Satoshi could potentially do so too (we have zero clue what's going on with satoshi in so many ways), so assuming that chaos was not the intention, I expect that if those coins ever did move, that's what would happen; starting at block ~50,000, then working backwards from there.
In such a sequence of events, it could be interpreted as a signal that those early miners are losing confidence in the safety of ECDLP protected coins. Of course, those people may have other reasons to not publicly announce why they're moving to different keys (which are not necessarily anything to do with the safety of the public key cryptography), so you are indeed correct; the lack of information will cause uncertainty, and the uncertainty will rock the Bitcoin ecosystem.
I hope such people (whether satoshi or not, there are others) are reading some of these discussions (it would surely be prudent to do so). If so, I also hope they will consider a slow and orderly move to new key types, and act sooner rather than later.
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.
Satoshi:
However, if something happened and the signatures were compromised (perhaps integer factorization is solved, quantum computers?), then even agreeing upon the last valid block would be worthless.
True, if it happened suddenly. If it happens gradually, we can still transition to something stronger. When you run the upgraded software for the first time, it would re-sign all your money with the new stronger signature algorithm. (by creating a transaction sending the money to yourself with the stronger sig)Nobody is asking why he did not move and is not moving these early mined unmoved P2PK coins:

Our guess is that he knew that the early mined coins will be moved one day. So he created a 'prize competition'. Otherwise he could move the coins to quantum resistant P2PKH addresses, but he did not and is not doing.
The only question is:
Nobody can stop that race.
The only question is:
Who will win the race and get the early coins?
Quantum computing or solving the "Satoshi Prize Competition".

December 2015 a Bitcointalk member discovered a puzzle transaction while playing around with his bot:
https://bitcointalksearch.org/topic/m.13381244
At that time nobody declared such a puzzle transaction which was created January 2015 until the creator of that competition came out 2 years later:
https://bitcointalksearch.org/topic/m.18765941
As of 01/10/2019 there are still more than 100 BTC to win. https://bitcointalksearch.org/topic/archive-bitcoin-challenge-discusion-5166284
We think that the early mined coins of Satoshi are also a prize competition and that Satoshi is waiting this coins to be moved. We also think that he will not respond after somebody moves the first coins but it will be a message to the Bitcoin community that the private keys are somehow on the blockchain. If Satoshi disagreed with that conclusion he would have moved the coins to other addresses.

* 100% sure that it is a prize competition
* 100% sure that you can solve it only with the blockchain
* still trying to solve it
* one day someone will solve it

Sergio says that the slope in the picture (This is Satoshi) https://bitslog.com/2013/04/17/the-well-deserved-fortune-of-satoshi-nakamoto/ is caused by restarting the application to mine (wallet) but it is possible that each 'black branch' represents one solution. That would avoid that only one winner gets the whole coins.
Yes, for sure Satoshi is one of the genius people
He would try to distribute the prize but let it still huge.
Satoshi might have predicted about the growth of technology over the years. Right now the first revolution of quantum computers have come to usage. To what extent this gonna get continued is unknown. Satoshi on realizing the growth only have made the network much strong years back. Even now it is strong that the bitcoin network can't be broken by the quantum computer that have been developed by Google.

I think Satoshi already knew that. that someday a quantum computer will exist. but he also had predicted, when it will be finished. supposing when satosi made it with the support of a quantum computer. then what is created is a blockchain with a higher level of security. it's just when blockchain and bitcoin are created. it has no support by super computers. I'm still surprised. how he created that complicated security without a quantum computer. while to decode the code that is made is the computer's need. Does Satoshi have a hidden quantum computer?
Antonopoulos: Google’s ‘Quantum Supremacy’ Has No Impact on Bitcoin

He makes it sound so easy.
Post-quantum cryptography calls for massively larger key and signature sizes. For example, a Lamport signature scheme would make transactions hundreds of times larger than now. It would be horrible for scaling.
Don't even get me started on the millions of lost or otherwise vulnerable outputs that won't be made quantum-safe by implementing a new algorithm.
Regarding quantum computers, they where a basic concept during the time of Satoshi but i doubt it would have been an influencing one for him - they still look like they aren't coming around for a couple years, and we don't need to worry about it yet.

As per experts, Quantum computers really becoming incredibly powerful, and it is more faster than Blockchain, but it is also believe that it will not break the blockchain industry, it will be hard to tell that right now and they can't see no real threat. If this will happen, it will count few decades before we can tell, so there is nothing to worry about for now.

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

1. Yes, with quantum computers they would become active. Did Satoshi think that quantum computers will exist?
In 2011, Satoshi isn't have a concrete view of what quantum computer is, basically, he knows a bit of info, but to the fact that it can interfere with the blockchain and cryptocurrency, I don't think so. But even though we know there's a risk abiding the creation of quantum computer and the blockchain, blockchain is strong enough to become secure and safe from attacks since the hashes are distributed across many miners around the globe.
