Answer: number of quantum gates grows exponentially, "allowing QCs [quantum computers] to factor 15 in 2001 with a total of 21 two-qubit entangling gates. Extrapolating from the used circuit, factoring 21 would require 2,405 gates, or 115 times more."

Implication: no, your 1024-bit encryption is not going to utterly break tomorrow. At least not because of quantum computing
