Embodiment Construction

[0047] The present disclosure provides a Rydberg atomic Rabi oscillation device and method, and the method includes: S1, separately turning on the probe light and coupling light to excite the atom from the ground state to the Rydberg atomic state through the Rydberg atomic Rabi oscillation device , the single photon of the detection light is absorbed by the atom, and the single photon detector does not detect the single photon signal; S2, turn off the coupled light adiabatically and wait for a time interval; S3, turn on the coupled light, the atom transitions to the excited state, and is subjected to Influenced by the storage time, the excited state transitions to the ground state and emits a photon. The single-photon preparation and high-fidelity multi-photon detection of Rydberg atoms prepared by the present disclosure have functions exceeding that of ordinary atoms, and will have broad application prospects in the field of quantum communication.

Abstract

The invention provides a Rydberg atomic pull ratio oscillation device and method. The method comprises the following steps: S1, respectively opening detection light and coupling light to excite atomsfrom a ground state to a Rydberg atomic state through the Rydberg atomic pull ratio oscillation device; S2, adiabatically turning off the coupling light and waiting for a time interval; and S3, opening the coupling light, enabling the atoms to jump to an excited state, and enabling the excited state to jump to a ground state and emit a photon under the influence of the storage time in the step S2.The Rydberg atom single-photon preparation and high-fidelity multi-photon detection prepared by the invention have the effects superior to those of common atoms, and have broad application prospectsin the field of quantum communication.

Description

technical field [0001] The disclosure relates to the field of quantum information, in particular to a Rydberg atomic Rabi oscillation device and method. Background technique [0002] Superatoms have great application prospects in the field of quantum information, because their interaction with light is stronger than that of ordinary atoms and light, and can be used to prepare single-photon sources and high-fidelity multi-photon detectors. [0003] At present, most of the research is on ordinary atoms, and there is no in-depth research on the field of superatoms. How to use superatoms to significantly improve the efficiency of atoms to absorb light will have greater application prospects in the future. Contents of the invention [0004] (1) Technical problems to be solved [0005] The present disclosure provides a Rydberg atomic Rabi oscillation device and method to at least partially solve the above technical problems. [0006] (2) Technical solutions [0007] According...
