This question already has an answer here:
Quantum computation is based on the superposition principle of quantum physics. Bits in a normal computer are either 0 or 1. Quantum physics allows bits to be in a superposition of 0 and 1, in the same way, Schrödinger’s cat can be in a superposition of “alive” and “dead.” [http://nautil.us]
My question is: Can public key cryptography survive quantum computers?
