IonQ paper claims 20,000 trapped-ion qubits could break ECDSA wallets before 2030

A Reddit post cites a new IonQ paper claiming its trapped-ion architecture could run Shor's algorithm against 256-bit ECDSA signatures with only 20,000 qubits in under a month, with such a machine projected before 2030.

What the sources claim

A new IonQ paper claims its trapped-ion architecture can run Shor's algorithm against 256-bit ECDSA signatures with only 20,000 qubits in less than a month.

“can be optimized to run Shor's algorithm against 256-bit ECDSA signatures (which underlie most cryptocurrencies) with only 20,000 qubits in less than a month”

The post claims the architecture requires only about 5 physical qubits per error-corrected logical qubit.

“requires only approximately 5 physical qubits per error-corrected logical qubit”

The post states a 10,000-qubit trapped-ion quantum computer is expected next year and a 20,000-qubit one before 2030.

“They are expected to release a 10,000-qubit trapped-ion quantum computer next year, with a 20,000 one coming before 2030”
