Bitcoin and quantum computing

[John Clark]

In 2012 it was estimated it would take a quantum computer one billion noisy physical quantum qubits to break 2048 bit RSA encryption. In 2019 that number was reduced to 20 million. Just one week ago a paper was published showing that a quantum computer would only need one million noisy physical qubits. Bitcoin uses elliptic curve cryptography not RSA but it's vulnerable to the same sort ofquantum attack.
