A Special Diamond Is the Key to a Fully Open Source Quantum Sensor


Quantum sensors can be used in medical technologies, navigation systems, and more, but they're too expensive for most people. That's where the Uncut Gem open source project comes in.

In a main-stage Defcon talk on Saturday, the pair will present an open source and affordable quantum sensor that can serve a variety of uses, from medical technologies to GPS alternatives. “You can do things you wouldn't have been able to do before, like using quantum sensors to start building portable MRI-style devices that can be used in all different countries,” Kumaran told WIRED ahead of the presentation. Software is vital in quantum sensing, because even the most refined and high-quality hardware still picks up noise in the environment that needs to be reconciled and filtered to focus the sensor's output on the intended detection.
