| Squeezed state continuous-variable quantum key distribution over 40 km fibre with local local oscillator | QCRYPT 2024 | Ivan Derkach, Hou-Man Chin, Adnan Hajomer, Nitin Jain, Ulrik L. Andersen, Vladyslav Usenko, Tobias Gehring |
Squeezed states of light promise significant advantages for enhancing the performance of continuous-variable quantum key distribution (CV-QKD) systems. These advantages include the ability to reach longer distances, tolerate higher levels of excess noise, and operate at lower information reconciliation efficiency. So far those advantages were only predicted in theory. In this work, we experimentally demonstrate a CV-QKD system over 40 km fibre using squeezed light achieving a secret key rate of 0.0318 bits per channel use, surpassing the equivalent coherent state system. Similar to state-of-the-art coherent state QKD systems our system employs digital signal processing for impairment compensation eliminating the need for complex locking mechanisms and enhancing its suitability for practical implementations. |
