• Google unveils Willow, a quantum computing chip with 105 qubits.

  • Willow can solve tasks in 5 minutes that would take supercomputers 10 septillion years.

  • Bitcoin’s security potentially at risk, but experts say it’s not an immediate threat.

  • Crypto community advises on preparing for future quantum threats.

Google’s Quantum Computing Leap

Google has introduced Willow, a quantum computing chip that has sent ripples through the tech and cryptocurrency communities. With 105 qubits, Willow can perform calculations in under five minutes that would take classical supercomputers an unimaginable 10 septillion years (1 followed by 24 zeros) to solve. This leap in computational power, as announced by Google, represents a significant milestone in quantum computing. But what does this mean for Bitcoin?

The Threat to Bitcoin’s Encryption

Bitcoin’s security relies heavily on cryptographic methods like SHA-256 for mining and ECDSA for transaction signatures. Here’s where the conversation gets interesting: Could Willow’s capabilities undermine these cryptographic safeguards?

Quantum computers, with their ability to handle multiple states simultaneously, could theoretically break current encryption methods. However, breaking Bitcoin’s encryption would require millions or billions of highly stable qubits, far beyond Willow’s current capacity.

On social media, some users expressed immediate concern. One tweet read, “Google’s quantum chip Willow really has that kind of power, it could change the whole game for mining.”

Yet, experts like Chris Osborn from the Solana ecosystem argue, “Google claims to have demonstrated ‘below threshold’ error correcting capabilities with their latest quantum chip, but true logical qubits, needed for actual decryption, are still elusive.”

Bitcoin’s Quantum-Resistant Measures

Despite the buzz, the immediate threat to Bitcoin from Willow seems overstated. Willow’s 105 qubits are a far cry from the millions needed to compromise Bitcoin’s encryption. According to researchers from the University of Sussex, you would need approximately 13 million qubits to break Bitcoin’s encryption in just one day.

Ethereum co-founder Vitalik Buterin has been vocal about preparing for quantum threats, suggesting measures like hard forks to update blockchain protocols. “Each piece of the Ethereum protocol that currently depends on elliptic curves will need to have some hash-based or otherwise quantum-resistant replacement,” he noted in an October blog.
