Quantum cameras could remake space-based intelligence

Can quantum physics enable better, cheaper, faster satellite photos? In a month or two, a startup will test a “quantum camera” for space-based imaging. If it works, it could slash the cost of missile defenses and give smaller NATO allies and partners spy-satellite capabilities that were once exclusive to major powers.

Funded in part by NASA and DARPA, the Boston-based Diffraqtion is testing a radically different way to make images from photons.

You might think that the cameras on the world’s most expensive satellites are fundamentally different from what your grandfather used to take old movies. But whether using chemicals and paper or chargeable transistors on a circuit, the process of deriving images from the behavior of photons has changed little in more than a century. That is one reason why space-based image collection—especially at high resolution—is incredibly expensive.

It’s also why Johannes Galatsanos, Diffraqtion’s ...
