WebOct 29, 2024 · This coherent trapping of the spin polarization is analogous to the mechanism of coherent population trapping (19, 20) in the sense that, in both cases, the system can be understood as a set of coupled oscillators that become effectively decoupled from one of their degrees of freedom (i.e., the optical transitions). WebOct 25, 2024 · We examine coherent population trapping in a circuit-QED system consisting of an Al/ AlO x /Al transmon qubit embedded in an Al three-dimensional cavity. By engineering the dissipation rate of the cavity to be much larger than that of the qubit and continuously pumping a two-photon process to an excited state of the cavity-qubit …
