Google veteran and blockchain CEO Graham Cooke confidently asserts that quantum computing will never破解 Bitcoin’s cryptographic security, despite the recent unveiling of quantum chips by tech giants like Microsoft, Google, and IBM. Addressing concerns over these advancements, Cooke emphasizes that Bitcoin’s underlying math is extraordinarily resilient, making any quantum attack practically impossible.
Microsoft’s Majorana 1 chip, introduced in early 2025, boasts the potential to scale to millions of qubits using “topoconductor” materials, stirring apprehension among crypto enthusiasts. Google’s Willow and IBM’s Blue Jay quantum processors further fuel speculation about the vulnerability of Bitcoin’s defenses. However, Cooke counters these fears with a compelling thought experiment: if every person on Earth (8 billion people) had a billion supercomputers each trying a billion combinations per second, it would still take more than 10^40 years to break Bitcoin—a timeframe astronomically longer than the universe’s 14-billion-year age.
Cooke highlights that a longer seed phrase dramatically increases security, explaining that a 24-word seed phrase contains 340 septillion trillion more combinations than a 12-word phrase. Even though Microsoft’s Majorana 1 uses stable topological qubits, which Cooke likens to “knots in rubber bands” that resist decoherence, such advances do not pose a meaningful threat to Bitcoin’s cryptographic foundation.
Meanwhile, the quantum computing arena is flourishing as governments and corporations worldwide ramp up investments. South Korea has pledged over $480 million across eight years for quantum technology research, while the UK committed more than $921 million targeting healthcare and energy sectors. Global quantum funding surged 125% in the first quarter of 2025, surpassing $1.25 billion. This influx of capital heralds transformative growth, with rapid technological breakthroughs and robust financial backing fueling the quantum race.
Despite the spectacular progress in quantum tech, Bitcoin’s cryptographic mathematics remain a mighty bulwark, reinforcing confidence that even the most futuristic quantum computers cannot compromise its security. As the quantum industry pushes forward at breathtaking speed, investors and crypto enthusiasts alike are reminded that the fortress guarding digital currency rests not merely on technology, but on enduring mathematical principles.
