The connection between the two is significant: the Oratomic team leverages Google’s quantum circuits, which are engineered to compromise 256-bit elliptic curve cryptography—an essential system for safeguarding Bitcoin and Ethereum wallets. Their research indicates that a neutral-atom configuration, utilizing laser-controlled atoms as qubits, has the potential to operate with approximately 1/50th of the qubit count that Google initially estimated.
Collectively, these studies represent one of the most substantial reductions in the anticipated timeline for quantum security threats. Over the past twenty years, the estimated requirements to execute Shor’s algorithm, the quantum approach to breaking public-key encryption, have drastically decreased from around 1 billion physical qubits in 2012 to roughly 10,000 today.
This progress clarifies potential timelines for future attacks.
According to the assumptions in the studies, a quantum system equipped with about 26,000 qubits could potentially unravel ECC-256 encryption—the standard safeguarding the Bitcoin and Ethereum blockchains—in as little as ten days. This capability would enable the quantum computer to extract private keys and seize control of funds.
For RSA-2048, commonly utilized by financial institutions to secure web2 platforms, an estimate of approximately 102,000 qubits would be needed, with a projected timeline of around three months in a highly efficient parallel setup. Elliptic curve cryptography is particularly vulnerable due to its ability to offer similar security with smaller key sizes, making it easier for a quantum machine to breach.
This estimated ten-day timeframe suggests that the rapid “on-spend” attack described in Google’s paper—where a quantum computer can break a key in mere minutes and intercept a live Bitcoin transaction—would be unlikely under these assumptions.
