Mainstream coverage will likely frame this as a threat to crypto security, but the reality is more nuanced: current quantum processors still have too few logical qubits and too high error rates to break RSA-2048 or ECDSA. However, each incremental improvement in error correction shrinks the estimated timeline for quantum advantage. For crypto markets, this adds a subtle headwind to long-term narratives around Bitcoin's immutability, especially as institutions begin pricing in quantum risk.

Experimental demonstration of quantum error-correcting codes combined with error detection and post-selection on a trapped-ion quantum processor shows improved logical error rates.
