Quantum communications technologies offer opportunities for unparalleled secure communications in both military and civilian settings. However, significant technological challenges exist at long distances due to signal loss, decoherence, and the lack of existing quantum repeaters to mitigate these effects. Quantum Encryption in Phase Space (QEPS) overcomes these challenges by uniquely leveraging quantum principles in a way that can be implemented on existing optical hardware and networks to establish quantum encrypted communications channels on commercially available infrastructure. This can be readily deployed for securing communications in the fields such as defense, telecom, government, financial services, etc to protect national security, critical infrastructure, and economic systems.
