Shulou(Shulou.com)11/24 Report--

On February 22, CTOnews.com announced that on February 25, the quantum-Hefei laboratory and exhibition hall for quantum key distribution in an 833km optical fiber channel will be open to Chinese citizens free of charge.

Visitors will be able to see the 833 km fiber channel quantum key distribution prototype that set a world record, as well as the quantum entanglement-teaching machine that attracted much attention at the Nobel Prize in Physics, and can also hear the story of the struggle of the researchers who set the 833 km world record. They can even simulate and experience quantum key distribution for the first time.

The free event will be held from 10:00 to 11:00 on February 25, with a limit of 20 people, although batches may be increased as before.

Anhui Mentian Quantum Technology Co., Ltd. is an enterprise directly under the Chinese Academy of Sciences, one of the first high-tech enterprises engaged in the industrialization of quantum information technology in China, and the only one in the field of cryptography with two academicians in both directions of quantum cryptography and classical cryptography. it has created world records for quantum technology many times, including the world's longest non-relay optical fiber quantum key distribution transmission distance of 833km and the world's leading 5GHz communication power.

The quantum key distribution of 833 km optical fiber channel not only sets a new record for optical fiber quantum key distribution, but also increases the safe transmission distance by more than 200 km. At the same time, it verifies the feasibility of building a ground quantum security network with long distance and high key transmission rate without relay, which provides a new technical way to promote the industrialization of wide-area and low-cost quantum secure communication.
