UrduOn March 11, PPPL opened its new Quantum Diamond Lab, a space devoted to studying and refining the processes involved in using plasma, the electrically charged fourth state of matter, to create high-quality diamond material for quantum information science applications.

Technique could improve the sensitivity of quantum sensing devices
In quantum sensing, atomic-scale quantum systems are used to measure electromagnetic fields, as well as properties like rotation, acceleration, and distance, far more precisely than classical sensors can.
Superdeep diamonds provide a window on supercontinent growth
Diamonds contain evidence of the mantle rocks that helped buoy and grow the ancient supercontinent Gondwana from below, according to new research from a team of scientists led by Suzette Timmerman.
Experiments at the National Ignition Facility probe carbon at record pressures
Decades of studies have shown that carbon’s crystal structure has a significant impact on material properties. In addition to graphite and diamond, the most common carbon structures found at ambient pressures, scientists have predicted several new structures of carbon that could be found above 1,000 gigapascals (GPa). These pressures, approximately 2.5 times the pressure in Earth’s core, are relevant for modeling exoplanet interiors but have historically been impossible to achieve in the laboratory. That is, until now. Under the Discovery Science program, which allows academic scientists access to Lawrence Livermore National Laboratory’s (LLNL) flagship National Ignition Facility (NIF), an international team of researchers led by LLNL and the University of Oxford has successfully measured carbon at pressures reaching 2,000 GPa (5 times the pressure in Earth’s core), nearly doubling the maximum pressure at which a crystal structure has ever been directly probed.
