Two-Beam Coupling Mechanism in Quantum Imaging with Four-Wave Mixing
Meng-Chang Wu, Nicholas R. Brewer, Rory W. Speirs, Kevin M. Jones, Paul D. Lett · 2019
We introduce a dual-seeding technique to cancel out the classical noise in a seeded four-wave mixing process. Two-beam coupling in the process can degrade quantum images. Seeding with skew rays can avoid the problem.
