In room-size metal boxes -secure against electromagnetic leaks, the National Security
Agency is racing to build a computer that could break nearly every kind of encryption used
to protect banking, medical, business and government records around the world.

According to documents provided by former NSA contractor Edward Snowden, the effort to
build “a cryptologically useful quantum computer” ? a machine exponentially faster than
classical computers ? is part of a $79.7 million research program titled “Penetrating Har
Targets.” Much of the work is hosted under classified contracts at a laboratory in
College Park, Md.
