Quantum Data Storage Gains Stability with Fibre Optic Error Correction
Researchers at the Technical University of Denmark have quantitatively analysed an all‑optical quantum memory that stores a qubit in a fibre loop and stabilises it via teleportation‑based error correction. By optimising the syndrome decoder, they predict logical infidelity below 1 % for storage times exceeding 400 ms at 17 dB squeezing. The study identifies a practical design rule—optimal correction‑node spacing largely independent of storage duration—and quantifies trade‑offs among photon loss, squeezing level, and correction frequency. These results provide concrete benchmarks for near‑term photonic quantum repeaters and scalable quantum networks.
