Abstract
Methods, devices, and systems are described for storing and transferring quantum information. An example device may comprise at least one semiconducting layer, one or more conducting layers configured to define at least two quantum states in the at least one semiconducting layer and confine an electron in or more of the at least two quantum states, and a magnetic field source configured to generate an inhomogeneous magnetic field. The inhomogeneous magnetic field may cause a first coupling of an electric charge state of the electron and a spin state of the electron. The device may comprise a resonator configured to confine a photon. An electric-dipole interaction may cause a second coupling of an electric charge state of the electron to an electric field of the photon.
