Abstract
The goal of this work is to develop Sb-based nBn infrared detectors operating at 2 µm with Quantum Efficiency (QE) exceeding 99%. These detectors have the potential to significantly increase the sensitivity of future generations of the Laser Interferometer Gravitational-Wave Observatory (LIGO) by exploiting quantum entanglement for sub-Poisson limited laser interferometry.
