NSA wants to use quantum computer to crack all encryption

What makes encryption so safe isn’t that it can’t be cracked, all encryption can be cracked, its the sheer amount of time and effort it would require to do so. Even with a powerful supercomputer, it could take years to crack a single, high-end encryption. This is something that the NSA hopes to change by building a quantum supercomputer that could, in theory, quickly crack nearly any encryption out there.
