In the first half of 2017, the technologies and products for quantum secure communications of QuantumCTek have assisted many large state-owned commercial banks such as Industrial and Commercial Bank of China and Bank of Communications to realize quantum encrypted transmission of core business data. Recently, the "Quantum + Financial" innovative applications achieved further great results. Based on the National Quantum Confidentiality Communications, i.e. the "Beijing-Shanghai Route", the Bank of China successfully applied the 1000-kilometer quantum confidential communications technology to realize quantum encrypted transmission of data from different places in Beijing and Shanghai. The quantum secured communications products from QuantumCTek deployed along the "Beijing-Shanghai Route" supported this application.
