Abstract: A quantum computing system includes a first silicon nitride resonator couplable to a first alkali atom, a second silicon resonator couplable to a second alkali atom, and a plurality of lasers for trapping, cooling, and manipulating the first alkali atom and the second alkali atom. Detectors detect a presence of the trapped first alkali atom and the trapped second alkali atom, and a processor is configured to receive at least one input signal from at least one of the detectors, the input signal indicating a presence of the trapped first alkali atom and the trapped second alkali atom, and, based on the received input, control at least some of the plurality of lasers to manipulate at least one of the trapped first alkali atom and the trapped second alkali atom to thereby generate photonic qubits using the trapped first alkali atom or generate entanglement between photonic qubits transmitted to the trapped second alkali atom.

Abstract: Generating photonic graph states includes positioning a plurality of quantum emitters at a plurality of coupling sites associated with a plurality of cavities and initializing a state of a quantum emitter qubit associated with each of the plurality of quantum emitters. Photonic qubits are transmitted toward the plurality of the quantum emitters a first instance transmission for generating an entangling gate between the photonic qubits and the quantum emitter qubit in order to entangle the quantum emitter qubit and the photonic qubits. Following the first instance transmission, photonic qubits are transmitted toward the plurality of quantum emitters in a one second instance transmission for generating a SWAP gate between the photonic qubits and the quantum emitter qubits to map the quantum emitter qubits to photonic qubits.

Abstract: A quantum device for interfacing Lanthanide ions with optical fields or microwave fields or both. The device includes waveguides or resonators or both for optical fields or microwave fields or for both. The device includes at least one surface to which a single customized Lanthanide molecular complex, or an ensemble, layer, multilayer or crystal of such, are attached or bonded. This places the Lanthanide ions within the optical or microwave fields or both. The ability to customize the molecular structure around each Lanthanide ion, and to control their orientation and position and nano-environment in general, enables minimizing the host lattice effects and non-radiative loss channels for each ion, and increasing their homogeneity. Accordingly, the advantages of the present invention include reduced inhomogeneities, narrower linewidths, extended fluorescence and coherence times, and higher operation temperatures. Devices which benefit from the present invention include lasers, amplifiers, sensors, quantum memories, repeaters and quantum information processing devices at optical fields, microwave fields, or both, including bi-directional optical-microwave convertors.
