When light hits a tiny defect embedded in a solid material like diamond or silicon carbide, it can kick the defect's electrons into an excited state. These spin defects have the potential to be used as stable, readable qubits for quantum technologies, for example, quantum sensing

When light hits a tiny defect embedded in a solid material like diamond or silicon carbide, it can kick the defect's electrons into an excited state. These spin defects have the potential to be used as stable, readable qubits for quantum technologies, for example, quantum sensing. But modeling the full physics of their energetics over time—a key step in developing spin defects into new technologies—is a challenging task.

Turning up the heat on chickpea yield

A University of Queensland study has outlined a practical pathway for accelerating the development of heat-adapted chickpeas using data from new 'omic' technologies. Ph.D. candidate Callum Jamie said the suite of technologies offered tremendous opportunities to understand how a c

Quantum sensor could measure how Earth drags spacetime

Einstein's theory of general relativity describes gravity as the bending of spacetime, a mathematical model that combines three-dimensional space and time into a single, four-dimensional continuum. The theory also predicts that a rotating object, such as Earth, slightly drags the

A quantum prediction from 1931 just came to life

Nearly a century after physicist Hans Bethe predicted them, scientists have created and directly observed unusual quantum states known as “Bethe strings” in an ultracold gas. By cooling cesium atoms to near absolute zero and trapping them in thousands of tiny one-dimensional tube
