Can quantum mechanics improve radar technology?

Press reports allude regularly to a “quantum advantage” in the field of long range detection of hidden targets or threats, which would have a substantial impact for the military. We’ve asked two world expert in the field to tell us about the science, the opportunities and the challenges. A great post by Giacomo Sorelli and Nicolas Treps from Laboratoire Kastler-Brossel and ONERA.

How to build quantum communication networks at a small scale ?

VeriQloud introduces in this great medium paper the feasibility of Quantum secured networks. Quantum key distribution (QKD) enables secret key establishment over an insecure communication channel. It even reaches the holy grail of encryption, which is unconditional security. No matter the effort spent by an eavesdropper, data encrypted through quantum key distribution remain secure forever.
