Quench, ABN AMRO and TNO Space are collaborating to test a quantum key distribution system called Measurement Device Independent Quantum Key Distribution (MDI-QKD). This new form of QKD will allow several users to connect with one another through a central measurement device and to exchange unique and complex codes. It’s virtually impossible to eavesdrop on this technology.
Qutech and ABN AMRO are also using a combination of different media to further boost security. The quantum connection is established by laser communication via existing fiber-optic connections (as was previously done by Qutech scientists) and by air or free space, via a method developed by TNO Space and Scientific Instrumentation.
The partners expect to be able to demonstrate a fundamentally secure data connection by the end of 2020.
