Physicists have created a new type of radar that could help improve underground imaging, using a cloud of atoms in a glass cell to detect reflected radio waves. The radar is a type of quantum sensor, an emerging technology that uses the quantum-mechanical properties of objects as measurement devices. —Sophia ChenIf you’re interested in the potential of quantum, why not check out:+ Why AI could eat quantum computing’s lunch. + This quantum computer built on server racks paves the way to bigger machines. + IBM aims to build the world’s first large-scale, error-corrected quantum computer by 2028.
