Google's Willow chip is so fast that it could theoretically decrypt Bitcoin in the future, but it's not quite there yet.
Bitcoin is still safe for now because quantum computers need millions of qubits to break it, and Willow only has about 100.
Cryptocurrency developers and researchers are already building quantum-resistant algorithms to stay ahead of these threats.
Google just dropped Willow, a quantum chip that defi re-creates the meaning of “fast” and “precise.” This isn’t your typical tech innovation.
Willow can do calculations in less than five minutes that would take the fastest supercomputer 10 septillion years to solve. That’s 10,000,000,000,000,000,000 years. Let that sink in.
But while tech enthusiasts celebrate, Bitcoin holders may want to sweat it out. Willow could, one day, dismantle the crypto fortress that keeps Bitcoin safe.
Bitcoin runs on cryptographic algorithms, unsolvable puzzles that protect the blockchain technology. Conventional computers can’t touch them. Quantum computers like Willow? That’s another story. With insane speed and improved error correction, quantum machines could turn the secure foundation of Bitcoin into a hacker’s playground. The real question isn’t if, but when.
Willow Mechanisms and Bitcoin's Shaky Defense
Regular computers use bits – ones and zeros – to process information. Quantum computers use qubits, which don’t work by the same rules. Qubits exist in multiple states at once, allowing them to explore countless solutions at once.
Imagine a maze: Your laptop tries one path at a time. A quantum computer? It takes each path once and is out before the laptop can finish tying its shoe.
This is where Willow shines. Not only is it fast, it is said to be very accurate as well. Until now, quantum systems have been wild, unstable, and error-prone.
“Part of the problem with qubits is that they are unstable and produce errors,” explains Tim Holbeck, technology strategist at DigiCert. “Willow has great error-correcting capabilities, which mitigates some of these issues.”

“Part of the problem with qubits is that they are unstable and produce errors,” explains Tim Holbeck, technology strategist at DigiCert. “Willow has great error-correcting capabilities, which mitigates some of these issues.”
But here’s where it gets scary for Bitcoin. The combination of speed and accuracy in Willow means that quantum chips could eventually break the encryption algorithms that Bitcoin and other cryptocurrencies rely on.
Bitcoin vs Quantum Timeline
Google employees aren’t exactly taking victory laps over Bitcoin’s grave. A company spokesperson was clear: “Willow’s chip is incapable of breaking modern crypto.”
This may sound reassuring, but here’s the thing: Everyone in Silicon Valley knows quantum computers are coming. The timeline? Five to 15 years, depending on progress. That’s not comforting if you’re counting on Bitcoin to stay untouched.
Park Fierbach, CEO of Radiant Commons, believes that even if Willow could theoretically speed up the cryptocurrency cracking process, it would take longer than the age of the universe for her to actually do so.
For reference, the universe is 13.7 billion years old. “There is almost no reason to use Willow in this technique in a way that would advance the trac timescale,” Feierbach sums up. “It would simply take too long.”
Here’s what Bitcoin believers can cling to: RSA, one of the cryptographic systems tied to Bitcoin’s security, is still secure—for now. Analysts estimate that cracking RSA would require about four million physical qubits. That’s millions, not hundreds like Willow currently has.

But the cryptocurrency industry isn’t just sitting around hoping quantum chips remain in development hell. They’re already working on defenses.
The National Institute of Standards and Technology (NIST) has introduced quantum-safe algorithms designed to resist attacks from quantum computers. These algorithms do not rely on the same cryptographic puzzles that quantum machines excel at solving.
Instead, they are built on mathematical problems that even the most advanced quantum chips struggle with. Google itself has been part of this effort, testing early versions of these quantum-safe solutions.
“The security community has long been aware of the expected timeline for breaking asymmetric encryption, and is working on defi standards,” a Google spokesperson said.
Taqi Raza, an assistant professor of electrical and computer engineering at the University of Massachusetts Amherst, believes this will lead to entirely new cryptocurrencies designed to be quantum-resistant. “New quantum cryptocurrencies will incorporate post-quantum cryptographic algorithms that are resistant to the computational power of quantum computers,” Raza said.
This is good news, but it comes with a caveat. Rehabilitating Bitcoin or Ethereum to adopt quantum-secure measures will not be easy.
The cryptocurrency industry is facing a strange paradox. On the one hand, quantum computing seems like a doomsday scenario for Bitcoin. On the other hand, it could propel the entire cryptocurrency ecosystem into a new era.
