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.
