In this section, we study the influence of the trusted noise on the efficiency of the QKD based on the loss control. The loss control approach relies on the assumptions associated with the properties of the fiber quantum channel. Firstly, Eve is…

Principle of the water display

The concept of the water-based display is illustrated in Fig. 1. A bi-layer water-air system is employed. By generating an acoustic field towards the water-air interface, interface deformations are expected⁶. The…

XRD characterization

XRD graphs of the \(\:{\text{L}\text{a}}_{2-\text{x}}{\text{s}\text{r}}_{\text{x}}\text{C}\text{o}{\text{O}}_{4}\) thin films are illustrated in Fig. 1. Accordingly, it has three main peaks in the region of 10 degrees to 70…

Spin blockade lifting via spin-orbit coupling

We use a p-type single-gate silicon transistor with light Boron channel doping, a system subject to strong SOC (Fig. 2a)⁴⁴. By applying a voltage on the top-gate (V_g) and back-gate (V_bg), we accumulate…

The system consists of a pump laser (Amphos 3102), and two distinct SWIR and MIR OPCPA modules arranged in parallel, with the entire arrangement fitting on a 1.5 m × 4.0 m optical table. Since each OPCPA requires only part of the total pump…
