A relatively simple plug-and-play control system of quantum key distribution (QKD) based on PCI7300 card is demonstrated, including mechanism design, key generation and key acquisition. The system works very well at the repetition frequency of 1 MHz, and
We report an experimental observation of the variation in linewidth of the electromagnetically induced transparency (EIT) resonance in a three-level Λ-type system for several laser bandwidths in a Rb vapor cell, with and without a buffer gas. It is found,
We propose a k-domain spline interpolation method with constrained polynomial fit based on spectral phase in swept-source optical coherence tomography (SS-OCT). A Mach–Zehnder interferometer (MZI) unit is connected to the swept-source of the SS-OCT system
