Single-particle–single-photon Coupling Using a Circuital Metamaterial Cavity
Qinghui Yan, Ron Ruimy, Arthur Niedermayr, Ido E. Kaminer · 2023
We propose a surface-plasmon-inspired circuital-metamaterial cavity that achieves record-breaking interaction strength between charged-particles and photons. The cavity drives emission of multiple microwave photons per particle, enabling strong particle-photon entanglement for applications in free-particles quantum optics.
