Invention:
This technology is an entanglement-assisted (EA) joint monostatic-bistatic quantum radar scheme that significantly outperforms similar conventional radars. The system has two radars: one with both a wideband entangled source and an EA detector and another with only an EA detector. An optical phase conjugation (OPC) is applied on the transmitter side, while classical detection schemes are typically applied to both receivers.
Background:
Quantum radars offer several advantages compared to their corresponding classical counterparts: improved receiver sensitivity, better detection probability of targets in a low signal-to-noise regime, improved synthetic aperture radar imaging quality, better resilience to jamming, and increased difficulty of detection are just some of the benefits.
However, quantum radars are difficult to implement in practice with noisy/lossy channels and decoherence plaguing the system. Even so, two common modern models have emerged: a quantum radar employing Lloyd’s quantum communication sensing concept and an interferometric quantum radar.
Applications:
- Secure communications
- Distributed quantum sensing
- Secure distributed quantum computing
Advantages:
- Exceeds classical channel capacities
- Outperforms classical sensor sensitivity
- Provides unconditional security for future networks
