Google Veteran Says Quantum Computing Can’t Crack Bitcoin
Google veteran and blockchain CEO Graham Cooke says quantum computing will never crack Bitcoin’s security. He made this claim despite recent advances in quantum chips from tech giants.
In a post on X, Cooke said Bitcoin’s cryptographic security is unbreakable. He dismissed concerns about Microsoft, Google, and IBM’s new quantum chips.
The Numbers Don’t Add Up for Hackers
Microsoft unveiled its Majorana 1 quantum chip in February 2025. The chip can scale to millions of qubits using “topoconductor” material. This sparked worry in the crypto community.
Google’s “Willow” and IBM’s “Blue Jay” also raised questions about Bitcoin’s defenses. But Cooke says critics underestimate Bitcoin’s math.
Cooke gave a thought experiment to show how hard cracking Bitcoin would be.
“Imagine this: 8 billion people. Each with a billion supercomputers. Each trying a billion combinations per second.The time needed? Over 10^40 years. The universe is only 14 billion years old.”
He explained that this math makes cracking Bitcoin impossible with any technology we can imagine.
“A 24-word seed phrase would need 340 septillion trillion more combinations than a 12-word phrase.”
Cooke also noted that regular qubits lose their state easily. Microsoft’s topological qubits in Majorana 1 are more stable. He compared them to “knots in rubber bands.”
These knots stay intact even when stretched or twisted. This stability could help quantum computers reach millions of qubits. But even this won’t threaten Bitcoin’s security. Bitcoin’s math remains an unbreakable barrier against quantum attacks.
Billions Pour Into Quantum Race
Quantum technology is experiencing explosive growth worldwide. Nations and corporations are pouring billions into research and development. Recent funding announcements highlight this accelerating trend across multiple countries.
South Korea pledged over $480 million across eight years for quantum computing. The UK committed more than $921 million for quantum healthcare and energy applications. Global quantum funding jumped 125% in Q1 2025 to exceed $1.25 billion.
This financial surge coincides with rapid technological advances in quantum computing. Substantial capital and breakthrough innovations create a powerful catalyst for development. The quantum industry is positioning itself for transformative growth across sectors.
