“…For instance, the EC3 and 3-SAT algorithms presented above are clearly adapted from the original adiabatic versions. Similar to the efforts to introduce ultra-fast adiabatic process in the adiabatic computing community, there are potential ways to further enhance the physics of resonant transitions [26,28,29], such as exploiting the additional quantum effects when multiple probe qubits are introduced.…”

In this article we assess a novel quantum computation paradigm based on the resonant transition (RT) phenomenon commonly associated with atomic and molecular systems. We thoroughly analyze the intimate connections between the RT-based quantum computation and the well-established adiabatic quantum computation (AQC). Both quantum computing frameworks encode solutions to computational problems in the spectral properties of a Hamiltonian and rely on the quantum dynamics to obtain the desired output state. We discuss how one can adapt any adiabatic quantum algorithm to a corresponding RT version and the two approaches are limited by different aspects of Hamiltonians' spectra. The RT approach provides a compelling alternative to the AQC under various circumstances. To better illustrate the usefulness of the novel framework, we analyze the time complexity of an algorithm for 3-SAT problems and discuss straightforward methods to fine tune its efficiency.

“…Although the resonant multiphoton excitation is now possible, it is difficult to separate the dominant single photon transition from the multiphoton transitions, and explore the quantum nonlinearity and its applications in the multiatom CQED system. Although the earliest observation of the vacuum Rabi splitting was reported in a CQED system with multiple atoms decades ago [1] and there are theoretical proposals to study the quantum nonlinear excitation in CQED systems with a few atoms [22][23], it is still elusive to attempt the experimental observation of the direct multiphoton transitions in a multiatom CQED system.…”

We propose a method to study the quantum nonlinearity and observe the multiphoton transitions in a multiatom CQED system. We show that by inducing simultaneously destructive quantum interference for the single-photon and two-photon excitations in the CQED system, it is possible to observe the direct three-photon excitation of the higherorder ladder states of the CQED system. We report an experiment with cold Rb atoms confined in an optical cavity and demonstrate such interference control of the multiphoton excitations of the CQED system. The observed nonlinear excitation of the CQED ladder states agrees with a theoretical analysis based on a fully quantized treatment of the CQED system, but disagrees with the semiclassical analysis of the CQED system. Thus it represents the first direct observation of the quantum nature of the multiatom CQED system and opens new ways to explore quantum nonlinearity and its applications in quantum optical systems in which multiple absorbers/emitters are coupled with photons in confined cavity structures.
