Google's Insights on Quantum Computers

I came across some info on Coindesk and wanted to share. If I got something wrong, feel free to let me know. So I heard about this new research from Google regarding quantum computers. I haven't read the whole thing, but apparently, it suggests that a future quantum computer could crack a bitcoin private key from its public key in just nine minutes. That’s kinda wild if true. This implies that quantum computers could potentially compromise unconfirmed transactions if they aren't finalized within that nine-minute window. We all know that sometimes it takes a while for bitcoin transactions to get confirmed, often longer than nine minutes.

Old FUD news. Ref https://bitcointalk.org/index.php?topic=5579141.msg66575228#msg66575228 for discussions about it. The last paragraph is quite important regarding 'news'...

Yes, there have been plenty of threads the past few days. Some of them: Be careful what you choose to believe about QuantumQuantum threat ignored by Bitcoin developersBitcoin Under Quantum Threat? New Google Data Warns About 2029 Deadline The critical nuance people are missing is that this is a resource estimate, not a demonstration. In other words, the paper tells us that "if you build this machine, here is what it costs". It does not tell us when that machine will exist. No quantum computer with anywhere near 500,000 physical qubits exists today. Google's current machines have on the order of ~100 physical qubits.
