Strong photon coupling to the quadrupole moment of an electron in a solid-state qubit
The fundamental concept of light–matter interaction is routinely realized by coupling the quantized electric field in a cavity to the dipole moment of a real or an artificial atom. A recent proposal1,2, motivated...
