16-QAM Quantum Receiver with Hybrid Structure Outperforming the Standard Quantum Limit
arXiv:1412.4486
Abstract
We present a quantum receiver for 16-QAM signals discrimination with hybrid structure containing a homodyne receiver and a displacement receiver, which can outperform the SQL, and the performance can be improved by an optimized displacement.
