• Abstract: Real-time CV-QKD receiver achieves peak 2.9 Mbit/s secret-key-rates over 12.8 km of fiber, while co-propagating 15 classical channels, separated 1 nm from the quantum signal. Performance degrades at higher launch powers due to crosstalk.

  Co-propagation of classical and quantum signals can benefit from the development of novel hollow-core fibers. We demonstrate a secure key rate of 330 bit/s for a quantum channel at 1538 nm in the presence of 25 x 10 Gb/s classical channels. We believe this to be an important step towards the deployment and integration of hollow-core fibers together with DV-QKD for the inherently secure telecom network of the future.

  We compare two key distillation techniques for satellite-based quantum key distribution. One is the traditional em non-blockwise strategy that treats all the signals as a whole. The other is a em blockwise strategy that divides the signals into individual blocks that have similar noise characteristics and processes them independently.

  Quantum key distribution (QKD) offers theoretical security based on the laws of physics. We present a novel approach to eavesdropper location that can be employed in quantum as well as classical channels. We demonstrate that our approach outperforms conventional OTDR in the task of localizing an evanescent outcoupling of 1% with cm precision inside standard optical fibers.

• DV-QKD Coexistence With 1.6 Tbps Classical Channels Over Hollow Core Fibre [2.300823901175652]
  coexistence transmission of 1.6 Tbps is achieved for the classical channels simultaneously with a quantum channel over a 2 km-long Hollow Core Nested Antiresonant Nodeless Fibre (HC-NANF) In the best-case scenario, the spacing between quantum and classical is 200 GHz (1.6 nm) with 50 GHz (0.4 nm) spacing between each classical channel. In the worst-case scenario using the same powers, and with 1 THz (8 nm) spacing between quantum and classical channels, the SKR dropped 10% using the HC-NANF, whereas in the SMF the SKR plummeted to zero.

Our proposal exhibits higher tolerance for noise in comparison to the standard receiver, thus enabling the distribution of secret keys in the condition of 4 dB-higher classical power.
