Cascaded Amplifying Quantum Optical Taps: A Robust Noiseless Optical Bus
Kamel Bencheikh, C. Simonneau, Juan Ariel Levenson · Physical Review Letters · 1997
Two identical amplifying quantum optical taps, based on noiseless optical parametric amplification and twin beam quantum correlation, have been implemented in a series configuration and experimentally investigated. The result is an optical bus which we have shown to be robust with respect to downstream losses.
