NSA seeks to build quantum computer that could crack most types of encryption - The Washington Post

Final paragraphs of a quantum computing reality check

"The budget for the National Intelligence Program, commonly referred to as the “black budget,” details the “Penetrating Hard Targets” project and noted that this step “will enable initial scaling towards large systems in related and follow-on efforts.”
Another project, called “Owning the Net,” is using quantum research to support the creation of quantum-based attacks on encryptions like RSA, documents show.
“The irony of quantum computing is that if you can imagine someone building a quantum computer that can break encryption a few decades into the future, then you need to be worried right now,” Lidar said."
