| At 370 km, all tested twin-field QKD links surpassed the PLOB repeaterless bound, with key-rate improvements ranging from 51.5% to 251.4%. | COMPARATIVE | Supported | 0.9781 | 1 of 4 | 121 |
| Across 20 client chips, 117 of 120 modulators functioned; their mean measured Vπ was 5.8 ± 1.4 V and interference visibility was 33.8 ± 5.6 dB. | QUANTITATIVE | Supported | 0.9781 | 1 of 4 | 96 |
| The study implemented pairwise twin-field QKD across 20 client chips and ten wavelength-multiplexed channels, with each channel reaching 370 km and a 3,700-km networking capability. | QUANTITATIVE | Supported | 0.9781 | 1 of 4 | 109 |
