Here's the quantum computer that can break the RSA scheme that blockchains rely on: New research
Previously, it was considered that a potential attacker would need millions of physical qubits to break the integrity of the aforementioned scheme, which is far beyond the current hardware capabilities of quantum computers.
Instead, the proposed algorithm can knock down barriers by factoring integers up to 48 bits with 10 superconducting qubits, the largest integer factored on a quantum device.As a result, a potential attacker needs 372 physical qubits to break the RSA-2048 scheme. To provide context, QuEra Computing device by physicists at Harvard and MIT has 256 qubits, while IBM's Condor is set to surpass the 1,000-qubit mark in 2023.
Other experts added that once this attack becomes real, blockchain teams will easily switch to more secure cryptographic schemes.to the media that he did not think"this will break RSA."Blockchain Analyst & Writer with scientific background. 6+ years in IT-analytics, 3+ years in blockchain.
