Research and Exploratory Development

Inventing the Future for APL and Our Nation

The Research and Exploratory Development (RED) Mission Area is Johns Hopkins APL’s research engine. We conduct pioneering research targeting game-changing breakthroughs to benefit national security missions. While each program within the RED Mission Area has a specific research focus, we recognize that innovation often happens at the intersection of technical disciplines. Therefore, we bring together multidisciplinary teams of talented scientists and engineers to tackle difficult challenges and invent the future for APL and our sponsors.

Engineering Tomorrow’s Quantum Computers

Researchers have touted the revolutionary potential of quantum computers to take on otherwise intractable challenges, like modeling complex molecular behavior for drug discovery or factoring enormous numbers in use for cryptography schemes. But how such a computer would be created remains unclear. With help from Johns Hopkins APL, the Defense Advanced Research Projects Agency is attempting to define, in practical terms, what a useful quantum computer looks like and how it must be built.
