The IBIT (iShares Bitcoin Trust) filing by BlackRock does mention quantum computing as a potential risk to Bitcoin. In its S-1 registration statement required by the SEC, BlackRock included this kind of disclosure: "The development of quantum computers could pose a risk to the security of the Bitcoin network, potentially rendering the cryptographic underpinnings of Bitcoin ineffective."
It is a potential risk to everyone not just Bitcoin like a sword of Damocles especially to the government.
But many seems to think that it's the kryptonite of Bitcoin
Anytime you hear about quantum computer, the next is crack bitcoin
You rarely (personally haven't) see any that states it would pose a threat to the financial system and government secrets.
The threat of quantum computers is often misunderstood as solely a Bitcoin issue, but its potential effect on the financial system and government secrets is a more pressing concern too. It's essential to recognize the sword of Damocles hanging over our entire digital infrastructure and work towards quantum-resistant cryptography.
By adopting quantum resistant cryptography government and other financial systems can proactively protect their systems and sensitive data from these threats but implementing these will require collaboration between both parties.
I like the phrase sword of Damocles but this is not something that can happen anytime soon and before we would see a quantum computer with the capacity to break BIP39 or ECDLP solve it, i believe it will take at least 50 years before that happens, that's why the current quantum computer don't have the 1% power to execute the task
If it eventually happens, almost every ecosystem will be in jeopardy.
I believe the reason why people mostly have their focus on Bitcoin when quantum computing is the topic is because they never understand the security of its mechanism.
Nevertheless, technology is advancing every day, and before quantum computing, which has the power to 100% guess the BIP39 seed phrase, there will be a solution.
