if you think it would take 100 years for qubit multiplexing to make a dent into ECC encryption...

this is the current estimate and assurance that ECC is currently impossible to crack.

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.

the Itoh-Tsujii method is not the primary means. Use of another number system is a lot faster.

I am no hater of whatever. The intent is simply to present what is the writing on the wall.
