Quantum illumination

Quantum illumination is a paradigm that uses quantum entanglement beneficially even if the original entanglement is completely destroyed by a lossy and noisy environment. Quantum illumination is a paradigm that uses quantum entanglement beneficially even if the original entanglement is completely destroyed by a lossy and noisy environment. Many quantum information applications, such as quantum teleportation, quantum error correction, and superdense coding, rely on entanglement. However, entanglement is a fragile quantum property between particles and can be easily destroyed by loss and noise arising from interaction with the environment, leading to quantum decoherence. Entanglement is therefore considered very hard to use in lossy and noisy environment.
