Optimizing photon mediated operations between disparate systems in quantum information processing

Optimal light-matter interfaces across qubits with initially different spectral signatures are of critical importance in the construction of scalable QIP platforms. In an effort to address this question, the community has used a variety of analytical and computational methods to investigate various protocols to boost the efficiency of various photon-mediated processes. One such protocol involves protecting the spectral signature of qubits from environmental noise to enable efficient entanglement generation, or two-qubit gates between disparate systems. To address the shortcomings of existing methods, we have implemented quantum algorithms compatible with existing NISQ (noisy intermediate scale quantum) systems, to solve fundamental quantum optics models describing photon-mediated operations in quantum information processing. Such solutions allow us to reliably characterize a variety of systems and protocols, and to assess the validity of conventional approximations that often limit the scope of analytical/numerical solutions. The quantum algorithms allow us to study under-explored regimes. They also provide, over a broad range of parameters, a reliable and intuitive characterization of physical systems, alongside a satisfactory agreement with various classical computing algorithms in their respective regimes of validity.
