Quantum Frequency Bridge: High-Accuracy Characterization of a Nearly-Noiseless Parametric Frequency Converter

Published

Author(s)

Ivan Burenkov, Sergey Polyakov

Abstract

We demonstrate an efficient and inherently ultra-low noise frequency conversion via a parametric sum frequency generation. Due to the wide separation between the input and pump frequencies and the low pump frequency relative to the input photons, the upconversion results in only $\approx$100 background photons per hour. To measure such a low rate, we introduced a dark count reduction algorithm for a transition edge sensor.
