Variational Quantum Demodulation for Coherent Optical Multi-Dimensional QAM

Not Accessible

Your library or personal account may give you access


We introduce a hybrid quantum-classical variational algorithms to realize quasi-ML decision of high-dimensional modulation (HDM) in fiber-optic communications, motivated by the recent advancement of quantum processors. Our Ising Hamiltonian model for demodulation is demonstrated on a real quantum processor.
