Satoshi-era bitcoin faces a bigger quantum threat after Google’s new.
Google says its Willow chip can prepare the special quantum states needed for advanced calculations with about 40 times fewer errors, reducing one of the hardware bottlenecks behind any future attempt to crack bitcoin wallets. Google says its Willow quantum chip has cut errors about 40-fold when preparing special states used in quantum calculations, tackling a costly step toward building machines powerful enough to crack bitcoin wallets. The result, published.
