arXiv:2503.19608 · doi:10.1103/tmsk-wrqy
The paper proposes a theoretical scheme for storing and retrieving microwave photons with near‑100 % efficiency over a 100 MHz bandwidth using a superconducting artificial chiral Λ‑type molecule coupled to a one‑dimensional transmission line.
Abstract
We theoretically investigate a high-efficiency and broadband microwave storage and retrieval scheme employing a superconducting artificial chiral molecule embedded in a one-dimensional transmission line. By optimizing the parametric coupling, the chiral -type molecule enables near 100\% storage efficiency and fidelity across a bandwidth of 100 MHz. Our results provide a feasible pathway toward implementing microwave quantum memories compatible with broadband quantum networks.
