    Abstract: A quantum computing system, method and computer readable medium involve a vacuum chamber, an atom source input associated with the vacuum chamber, a Photonic Integrated Circuit (PIC) having an interaction region configured to interact with an atom from the atom source, a coupling location for atom positioning, a trapping laser for trapping the atom in the coupling location, an excitation laser for manipulating an electronic state or a nuclear state of the atom, a waveguide for guiding input light to the coupling location, and an output channel for directing quantum light generated at the coupling location, out of the vacuum chamber as a resource for quantum computing. The coupling location is associated with the PIC, and the interaction region of the PIC is arranged for at least partial exposure to the vacuum.

    Abstract: A quantum computing system, method, and computer readable medium involves initializing a state of a resonator-coupled quantum emitter having at least four levels arranged in an N-configuration, the N-configuration having a first ground state, a second ground state, a first excited state and a second excited state. A frequency of a first transition between the first ground state and the first excited state is tuned, a frequency of a second transition between the second ground state and the second excited state is tuned, and a frequency of a third transition between the second ground state and the first excited state is tuned. A plurality of photons are fed at a frequency corresponding to the frequency of the second transition, thereby entangling the plurality of photons to the resonator-coupled quantum emitter. Likewise, a photon at a frequency corresponding to the frequency of at least one of the first transition or the third transition is fed, thereby mapping a state of the resonator-coupled quantum emitter into a photon.

    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.
