#谷歌量子芯片削减量子错误40倍
👉 量子算力逼近，老钱包咋办
Google has taken another step forward in quantum computing.
The results were published in Science this week.
The star of the show is the Willow chip.
The chip reduced errors in magic-state preparation by about 40 times.
The magic states that passed screening had a fidelity of 99.99%.
The trade-off is that only about 8 out of every 100 attempts make it through.
The rest are discarded during error checks.
Researchers say a larger demonstration has yet to be done.
Magic states are a key consumable in quantum machines.
Some estimates suggest they could consume 95% of computing power.
Reducing this cost could bring forward the timeline for the whole machine.
The risk falls on old Bitcoin addresses.
The public keys of early wallets have been sitting on the blockchain for years.
In theory, a sufficiently powerful machine could derive the private keys.
Addresses whose keys have been exposed are first in line.
Opinions in the industry are divided.
One side says there is no urgent threat right now.
The other says the timeline now looks more credible.
The debate centers on the scale of error correction.
A publicly listed U.S. exchange announced migration priorities this week.
In crypto, upgrade costs will fall first on custodians.
ETF addresses will have to change too.
How long do you think this round of upgrades will take? Let’s talk in the comments.
