Why is 128-bit AES Insecure for a Quantum Computer, But 256-bit Is Not?

An interesting explanation for those who really want to know why 128-bit AES is insecure for a Quantum Computer whereas 256-bit AES is not.

To fight the power of doubling sets, double your set!

@Early_Adopter    This may work for RSA 2048-bit keys to 4096 bit - but apparently some are predicting 2025 could the be big year for Q-Day instead.  A year earlier.

Yea there are much faster exponentials than doubling sets

Though I mean it’s probably already happened somewhere and the sneaky-beakies somewhere are sitting on it enjoying the intel edge…
