Google's 40x improvement in quantum computing error rates raises concerns about future Bitcoin security, despite current limitations. Bitcoin (BTC) is trading at $81,628.00, down 0.1% since this brief published. This is an original TLT brief based on reporting by CryptoNews, with live market data added, as of Sun, 18 Oct 2026 06:00:04 UTC.
This development highlights the potential future threat of quantum computing to Bitcoin's cryptographic security, even though practical risks remain distant.
- Google achieves a 40x reduction in quantum computing errors, reaching 99.9% accuracy.
- Current quantum machines are still far from breaking Bitcoin's cryptographic signatures.
- The advancement reignites discussions about quantum resistance in blockchain technology.

Google has announced a significant advancement in quantum computing, achieving a 40-fold reduction in error rates and reaching 99.9% accuracy, according to CryptoNews.
This development has rekindled concerns about the potential future threat of quantum computing to 
Bitcoin's cryptographic security, as quantum machines could theoretically break the encryption that underpins the cryptocurrency.
However, CryptoNews clarifies that current quantum computers are still far from being able to break Bitcoin's cryptographic signatures, suggesting that practical risks remain distant.
The news comes amid growing awareness of the need for quantum-resistant cryptography in blockchain technology, as the industry seeks to future-proof its systems against the potential capabilities of quantum computing.
In the broader market context, Bitcoin's price has remained relatively stable, with a 0.25% increase over the past 24 hours, trading at $81,718. The overall crypto market cap stands at $2.81 trillion, with a Fear & Greed index of 53, indicating a neutral sentiment.
Since this brief published about 48 hours ago, Bitcoin (BTC) has moved from $81,718.00 to $81,628.00 — -0.11%.
The chart plots BTC's price: grey is the move before this brief published, the vertical dashed line marks the moment it published, the horizontal dashed line is the price then, and the coloured area is the move since — from TLT's market data (daily resolution). It shows what happened after the news, not that the news caused it; many factors move prices. Not financial advice.
At today's peer-to-peer rate, 1 BTC ≈ ₦111.51M (about $81,628.00), up 0.2% over 24 hours. The naira itself trades about 2.5% above the official rate on the P2P market, so a Nigerian buyer's effective cost differs from the headline dollar price.
