Quantum Computing Research Suggests Bitcoin's Cryptography Could Be Vulnerable With 30K Qubits
New research indicates that breaking Bitcoin's encryption may require fewer quantum computing resources than previously thought.
New research indicates that breaking Bitcoin's encryption may require fewer quantum computing resources than previously thought. Bitcoin (BTC) is trading at $80,754.00. This is an original TLT brief synthesising 2 outlets (Bitcoin.com, CryptoPotato), plus live market data, as of Thu, 29 Oct 2026 19:15:03 UTC.
This development underscores the urgency for the cryptocurrency industry to prepare for quantum threats, as it suggests Bitcoin's security could be compromised sooner than expected. The findings could accelerate efforts to develop quantum-resistant cryptographic solutions.
- Research estimates 30,000 qubits could break Bitcoin encryption in one hour.
- Current quantum computers are far from this capability, but progress is accelerating.
- The findings highlight the need for quantum-resistant cryptography in crypto.
Bitcoin.com and CryptoPotato both report that Alice & Bob's research suggests 30,000 qubits could break Bitcoin's cryptography in one hour, assuming cat qubits with minimal bit-flip errors. While CryptoPotato mentions that Alice & Bob's largest current demonstrator uses a 12-qubit chip, Bitcoin.com focuses on the broader implications for Bitcoin's security. Both outlets emphasize the urgency of developing quantum-resistant solutions but differ slightly in their emphasis on the current state of quantum computing technology.

New research from quantum computing company Alice & Bob suggests that the cryptography protecting the 
Bitcoin network could be vulnerable with far fewer quantum computing resources than previously estimated. The researchers claim that 30,000 qubits could potentially break Bitcoin's encryption within one hour, assuming the use of cat qubits that exhibit exceptional stability with minimal bit-flip errors.
This estimate is significantly lower than some earlier predictions, which had suggested that breaking Bitcoin's encryption would require millions of qubits. The research adds a new layer of urgency to the ongoing discussions about the threat of quantum computing to cryptocurrencies.
While Alice & Bob's research indicates a potential vulnerability, it's important to note that current quantum computers are still far from achieving the 30,000-qubit threshold. The company's largest demonstrator currently operates on a 12-qubit chip, as reported by CryptoPotato. However, the rapid pace of advancements in quantum computing technology means that the threat could become more imminent in the coming years.
The findings have significant implications for the cryptocurrency industry, which relies heavily on the security of cryptographic algorithms. The research underscores the need for the development of quantum-resistant cryptographic solutions to ensure the long-term security of digital assets like Bitcoin.
In the current market context, Bitcoin is trading at $80,739, showing a slight 24-hour decline of 0.26% and a 7-day decrease of 0.48%. The total crypto market cap stands at $2.77 trillion, with a neutral Fear & Greed index of 51. While the immediate market impact of this research is minimal, it raises important questions about the future security of cryptocurrencies.
Since this brief published about 4 hours ago, Bitcoin (BTC) has moved from $80,739.00 to $80,754.00 — +0.02%.
