Countermeasure for Negative Impact of a Practical Source in Continuous-Variable Measurement-Device-Independent Quantum Key Distribution

Luyu Huang et al.

Summary: Continuous-variable measurement-device-independent quantum key distribution (CV-MDI QKD) is able to defend against all attacks on the measurement devices. However, the imperfections of the actual source pose practical security risks to the CV-MDI QKD system. We propose a countermeasure based on the one-time-calibration method to eliminate the negative impact of the actual source, improving the practical security of the CV-MDI QKD system.

Continuous-mode quantum key distribution with digital signal processing

Ziyang Chen et al.

Summary: Continuous-variable quantum key distribution (CVQKD) offers the advantage of sharing keys remotely using standard telecom components, which makes it cost-effective and high-performance for metropolitan applications. However, the introduction of high-rate spectrum broadening has led to the adoption of modern digital signal processing (DSP) technologies to recover quadrature information from continuous-mode quantum states. The security proof of DSP involving multi-point processing is missing. In this paper, a generalized method using temporal modes theory is proposed to analyze continuous-mode state processing via linear DSP, reducing the security proof to single-mode scenarios and paving the way for classical compatible digital CVQKD.
