Quantum calculations reveal how spin defects lose energy

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

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 surrounding spacetime as it rotates, a phenomenon known as frame-dragging.Quantum Physics NewsRead More
