Atomic-scale defects in 2D materials show terahertz spin splitting, pointing to robust spin qubits and single-photon emitters at higher temperatures. (Nanowerk News) Scientists from the National ...

Terahertz (THz) waves, which are located between microwaves and infrared light in the electromagnetic spectrum, can pass through many materials without causing damage, making them useful for security ...
