Testbed Map for Quantum Communication in Germany
SQuaD is the central point of contact for the expertise and infrastructure of Quantum Communication in Germany. For this purpose, actors from research and industry are brought together and the existing research set-ups of the partners are expanded to include public use of testbeds for Quantum Communication Technology.
The testbed map shows the locations in Germany where testbeds in the field of Quantum Communication exist or are planned. If your existing or required testbed is not yet included in the map, please contact us at squad@ptb.de.
