The colder you make something the longer you can postpone quantum decoherence, and quantum decoherence is the major roadblock to building a quantum computer of a few hundred Qubits. If a machine like that could be built the world would change so dramatically that it would soon become unrecognisable. Besides extreme cooling another approach toward quantum computing is to use non-Abelian Anyons, these are 2 dimensional quasiparticles that are far more resistant to quantum decoherence than electrons or photons or any other known particle. We don't know for certain that non-Abelian Anyons exist but there is mounting evidence that they do. Microsoft of all people is pursuing this approach.
