Claim Text:
1. An electro-optical system for directly exchanging quantum information between optical qubits and superconducting qubits comprising: a superconducting microwave cavity; an electro-optic material positioned inside of the superconductive microwave cavity for directly coupling optical photons to the superconducting qubits; a superconducting qubit circuit formed on the electro-optic material including a 3-dimensional (3D) superconducting qubit having two electrodes; a dipole antenna, formed on the electro-optical material by the two electrodes attached to the superconducting qubit circuit and including a Josephson junction, for directly coupling the 3D superconducting qubit to the superconducting microwave cavity; an optical photon input for receiving input optical photons; a microwave photon input for receiving input microwave photons; a microwave photon output for outputting microwave photons; and an optical photon output for outputting optical photons that are entangled with the 3D superconducting qubit or that are modulated by a state of the 3D superconducting qubit to directly transfer quantum information between optical and microwave photons.
