Abstract

We stabilized relative phase fluctuations of the photon channel using dual-band stabilization in twin-field quantum key distribution. The integrated phase noise was improved from 230 mrad to 100 mrad with laser frequency stabilization.

Enhancing dual-band stabilization for twin-field quantum key distribution using laser frequency stabilization

Abstract Twin-field quantum key distribution (TF-QKD) has attracted considerable attention in quantum communication for the extension of secure communication distance. In TF-QKD, precise photon phase control is required and has been realized using dual-band stabilization (DBS). In this study, we performed residual phase noise reduction in DBS using laser frequency stabilization. The achieved frequency stability of the light sources was better than 1 × 10 −12 when the averaging time is larger than 1 s, indicating that the laser frequency variation was less than 200 Hz at 1.5 μm. The integrated phase noise at 1 s was less than 200 mrad, and the corresponding quantum bit error rate at 1 s was less than 1% after applying laser frequency stabilization. This result demonstrates that the stringent phase stability requirements in TF-QKD can be achieved without relying on complex optical frequency combs, enabling a simpler and more cost-effective experimental setup.

Phase stabilization with triple wavelength bands for single-photon interference in quantum communication

Yohei Sugiyama, Akito Ozawa, Wataru Kokuyama +3 more

Optical interferometers are crucial for long-distance quantum communications. We propose a novel phase stabilization method employing triple wavelength bands for single-photon interference in optical fiber-based interferometers, incorporating a simplified laser frequency stabilization technique that utilizes a single nonlinear crystal. After stabilization, the residual phase noise of the fiber interferometer was 20 mrad for differential arm lengths (Δ L ) of 0 and 10 m. This represents a 9-fold and 7.5-fold improvement for Δ L = 0 and 10 m, respectively, compared with those observed in previous double-wavelength methods. These findings enhance the visibility and simplicity of quantum key and entanglement distributions in long-distance quantum communication.

Independent-optical-frequency-comb-powered 546-km field test of twin-field quantum key distribution

Twin-field quantum key distribution exploits single-photon interference to provide long-haul secure communication. However, real-time phase tracking between optical signals sent from opposite ends of the communication link is necessary to realize this scheme. Here the authors show that it is feasible to apply independent optical frequency combs in a quantum communication field trial, using a coherent dual-band stabilization technique. A practical finite-size-secure-key rate of 0.53 bit/s is recorded over a 546-km link connecting two major cities in China. This study represents a significant setup toward the integration of long-distance fiber links into quantum networks.

Simultaneous frequency stabilization of two 1550-nm lasers at single-photon level

Bo 波 Yu 于, Zhen−Qiang Yin, Weijie Ding +2 more

Abstract The twin-field quantum key distribution (TF-QKD) requires that two lasers hundreds of kilometers apart must have the same frequency to achieve the high single-photon interference visibility. This means that both lasers need to be stabilized to the same frequency reference. A simple and robust system is presented for simultaneously stabilizing two 1550-nm lasers at the single-photon level. By utilizing the single-photon multi-frequency modulation technology, both the fiber laser and distributed feedback (DFB) laser are stabilized to the π -phase shifted fiber Bragg grating at the same time. The frequency fluctuations of fiber laser and DFB laser are bounded within 1.39 MHz and 1.53 MHz over 2000 s, respectively. These two frequency-stabilized 1550-nm lasers could be used for TF-QKD.

Frequency-matching quantum key distribution

Hao-Tao Zhu, Yizhi Huang, Abdullah Rasmita +5 more

Quantum key distribution (QKD) enables information-theoretically secure communication against eavesdropping. However, phase instability remains a challenge across many QKD applications, particularly in schemes such as twin-field QKD and measurement-device-independent QKD. The most dominant source of phase fluctuation arises from the frequency offset between independent lasers. Here we propose a method to address this issue by employing a classical photodiode to compensate for the laser frequency difference. As an application of this method, we implement this technique in a mode-pairing QKD system, achieving an error rate approaching the theoretical limit and surpassing the linear key-rate bound over a fiber distance of 296.8 km. This approach provides a practical solution for frequency matching between independent lasers and can be extended to other fields requiring precise phase stabilization.
