Microwave Quantum Illumination

9 May, 2020 – Shabir Barzanjeh

Our paper Microwave quantum illumination using a digital receiver has been published. In this work we experimentally investigate the concept of quantum illumination at microwave frequencies. We generate entangled fields to illuminate a room-temperature object at a distance of 1 m in a free-space detection setup. We implement a digital phase-conjugate receiver based on linear quadrature measurements that outperforms a symmetric classical noise radar in the same conditions, despite the entanglement-breaking signal path.
