Satoshi-era bitcoin faces a bigger quantum threat after Google’s new Willow breakthrough

60-second summary

Google reports its new Willow quantum chip prepares special quantum states for advanced calculations with roughly forty‑times fewer errors, dramatically easing a major hardware bottleneck for future attacks on Bitcoin’s cryptography; the improvement raises concerns that Satoshi‑era Bitcoin could face a more viable quantum‑based threat, prompting industry calls for accelerated post‑quantum security upgrades.
