Nobody is 'avoiding' that research. People already know a fast quantum algorithm exists for the factorization problem, which is the core of RSA. hence, people are already working on cryptosystems more computationally complex than RSA. Hell, even more computationally intensive than what quantum computers are thought to be able to do. The class of algorithms called lattice based cryptography are known to be impossible for quantum computers to break, even though these are fully classical methods of cryptography.
