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
Anything you hear a 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.
