How many qubits would it take to break Bitcoin's encryption?

[VB]

Genuine question, is there an actual number of qubits that would be needed to crack Bitcoin's cryptography?

[Beth]

Estimates generally range from several thousand to a few hundred thousand physical qubits depending on the error correction approach used, current quantum computers sit around 1,000 to 1,500 physical qubits, so there's still a real gap. That required number has been shrinking over time though as error correction techniques improve, which is why the estimate isn't a fixed target
