Quantum radar, quantum networks, not-so-quantum hackers

Many quantum technologies, such as quantum computers, rely on a phenomenon called entanglement. One reason why quantum networks are being studied is because they can distribute entanglement to their users. In this paper, we describe how quantum radars, particularly the recently-developed quantum two-mode squeezing radar (QTMS radar), can be used with quantum networks. On a related note, we also point out how QTMS radar can be vulnerable to interception if an adversary has access to the measurement record that the radar uses to distinguish signal from noise.
