Mode Mismatch: A Hidden Weakness in Quantum Key Distribution

21.12.2025 by Ray Dalio

The presented model demonstrates an equivalence between phase-matching (PM) and Einstein-Brillouin (EB) approaches to continuous-variable measurement-device-independent quantum key distribution, revealing that data correction within the PM framework corresponds to displacement operations in the EB model and necessitates precise mode-matching coefficients for optimal performance under continuous-mode scenarios, akin to performing heterodyne detection on a squeezed vacuum state.

New research reveals that imperfect alignment of light’s temporal modes can significantly reduce the secure key rate in continuous-variable quantum key distribution systems.
