Quantum key distribution platform from ID Quantique offers high-speed key generation
The Clavis3 QKD Platform provides quantum key distribution for research and development applications. It offers high-speed key generation and allows secure key exchange for up to 100 km. It uses a high-bit-rate coherent one-way protocol. Key distillation steps are implemented in a FPGA.

![FIGURE 1. In this example of an optical-fiber-based QKD system, the quantum (open) channel is in blue (black). SPD0 and SPD1 are single-photon detectors. Each bit is encoded by a pair of pulses—in phase (antiphase) pulses are separated by nλ ([n+½]λ), where n is an integer and λ is the wavelength of the light, and lead to a detection at SPD0 (SPD1). If Eve tries to measure this separation and resend a copy, she will sometimes change it (see rightmost pair of pulses) and cause a detection in the ‘wrong’ detector.](https://img.laserfocusworld.com/files/base/ebm/lfw/image/2019/01/1901lfw_chu_f1.png?auto=format,compress&fit=crop&q=45&h=139&height=139&w=250&width=250)
