Breaking 256-bit Elliptic Curve Encryption with a Quantum Computer - Schneier on Security
Researchers have calculated the quantum computer size necessary to break 256-bit elliptic curve public-key cryptography: Finally, we calculate the ...
 this is the paper that describes on page 12, Section 3.4.2, how multiplexed processing negates the requirement for physical large number of qubits. 📄.pdf the Itoh-Tsujii method is not the primary means. Use of another number system is a lot faster.
